CPACK-GENERATORS(7) CMake CPACK-GENERATORS(7)

NAME

cpack-generators - CPack Generator Reference

GENERATORS

CPack Archive Generator

CPack generator for packaging files into an archive, which can have any of the following formats:

  • 7Z - 7zip - (.7z)
  • TBZ2 (.tar.bz2)
  • TGZ (.tar.gz)
  • TXZ (.tar.xz)
  • TZ (.tar.Z)
  • TZST (.tar.zst)
  • ZIP (.zip)



Added in version 3.1: 7Z and TXZ formats support.

Added in version 3.16: TZST format support.

When this generator is called from CPackSourceConfig.cmake (or through the package_source target), then the generated archive will contain all files in the project directory, except those specified in CPACK_SOURCE_IGNORE_FILES. The following is one example of packaging all source files of a project:

set(CPACK_SOURCE_GENERATOR "TGZ")
set(CPACK_SOURCE_IGNORE_FILES


  \\.git/


  build/


  ".*~$"
)
set(CPACK_VERBATIM_VARIABLES YES)
include(CPack)


When this generator is called from CPackConfig.cmake (or through the package target), then the generated archive will contain all files that have been installed via CMake's install() command (and the deprecated commands install_files(), install_programs(), and install_targets()).

Variables specific to CPack Archive generator

Package file name without extension.
The default is <CPACK_PACKAGE_FILE_NAME>[-<component>], with spaces replaced by '-'.

The extension is determined from the archive format (see list above) and automatically appended to the file name. Note that <component> is all uppercase in the variable name.

Added in version 3.9: Per-component CPACK_ARCHIVE_<component>_FILE_NAME variables.


Added in version 3.25.

Package file extension.

Default values are given in the list above.


Enable component packaging.
OFF

If enabled (ON) multiple packages are generated. By default a single package containing files of all components is generated.


Variables used by CPack Archive generator

These variables are used by the Archive generator, but are also available to CPack generators which are essentially archives at their core. These include:

  • CPack Cygwin Generator
  • CPack FreeBSD Generator

The number of threads to use when performing the compression.

Added in version 3.18.

1

If set to 0, the number of available cores on the machine will be used instead. The default is 1 which limits compression to a single thread. Note that not all compression modes support threading in all environments. Currently, only the XZ compression may support it.

See also the CPACK_THREADS variable.

Added in version 3.21: Official CMake binaries available on cmake.org now ship with a liblzma that supports parallel compression. Older versions did not.


CPack Bundle Generator

CPack Bundle generator (macOS) specific options

Variables specific to CPack Bundle generator

Installers built on macOS using the Bundle generator use the aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following Bundle-specific parameters (CPACK_BUNDLE_xxx).

The name of the generated bundle. This appears in the macOS Finder as the bundle name. Required.

Path to an macOS Property List (.plist) file that will be used for the generated bundle. This assumes that the caller has generated or specified their own Info.plist file. Required.

Path to an macOS icon file that will be used as the icon for the generated bundle. This is the icon that appears in the macOS Finder for the bundle, and in the macOS dock when the bundle is opened. Required.

Path to a startup script. This is a path to an executable or script that will be run whenever an end-user double-clicks the generated bundle in the macOS Finder. Optional.

Added in version 3.2.

The name of your Apple supplied code signing certificate for the application. The name usually takes the form Developer ID Application: [Name] or 3rd Party Mac Developer Application: [Name]. If this variable is not set the application will not be signed.


Added in version 3.2.

The name of the Property List (.plist) file that contains your Apple entitlements for sandboxing your application. This file is required for submission to the macOS App Store.


Added in version 3.2.

A list of additional files that you wish to be signed. You do not need to list the main application folder, or the main executable. You should list any frameworks and plugins that are included in your app bundle.


Added in version 3.3.

Additional parameter that will passed to codesign. Default value: --deep -f


Added in version 3.2.

Path to the codesign(1) command used to sign applications with an Apple cert. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).


CPack Cygwin Generator

Cygwin CPack generator (Cygwin).

Variables affecting the CPack Cygwin generator

•
Added in version 3.18: CPACK_ARCHIVE_THREADS


Variables specific to CPack Cygwin generator

The following variable is specific to installers build on and/or for Cygwin:

The Cygwin patch number. FIXME: This documentation is incomplete.

The Cygwin patch file. FIXME: This documentation is incomplete.

The Cygwin build script. FIXME: This documentation is incomplete.

CPack DEB Generator

The built in (binary) CPack DEB generator (Unix only)

Variables specific to CPack Debian (DEB) generator

The CPack DEB generator may be used to create DEB package using CPack. The CPack DEB generator is a CPack generator thus it uses the CPACK_XXX variables used by CPack.

The CPack DEB generator should work on any Linux host but it will produce better deb package when Debian specific tools dpkg-xxx are usable on the build system.

The CPack DEB generator has specific features which are controlled by the specifics CPACK_DEBIAN_XXX variables.

CPACK_DEBIAN_<COMPONENT>_XXXX variables may be used in order to have component specific values. Note however that <COMPONENT> refers to the grouping name written in upper case. It may be either a component name or a component GROUP name.

Here are some CPack DEB generator wiki resources that are here for historic reasons and are no longer maintained but may still prove useful:




List of CPack DEB generator specific variables:

Enable component packaging for CPackDEB
No
OFF

If enabled (ON) multiple packages are generated. By default a single package containing files of all components is generated.


Set Package control field (variable is automatically transformed to lower case).
Yes
  • CPACK_PACKAGE_NAME for non-component based installations
  • CPACK_DEBIAN_PACKAGE_NAME suffixed with -<COMPONENT> for component-based installations.


Added in version 3.5: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME variables.

See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-source


Added in version 3.6.

Package file name.

Yes
<CPACK_PACKAGE_FILE_NAME>[-<component>].deb

This may be set to:

Tell CPack to automatically generate the package file name in deb format:

<PackageName>_<VersionNumber>-<DebianRevisionNumber>_<DebianArchitecture>.deb


This setting recommended as the preferred behavior, but for backward compatibility with the CPack DEB generator in CMake prior to version 3.6, this is not the default. Without this, duplicate names may occur. Duplicate files get overwritten and it is up to the packager to set the variables in a manner that will prevent such errors.

<file-name>[.deb]
Use the given file name.

Changed in version 3.29: The .deb suffix will be automatically added if the file name does not end in .deb or .ipk. Previously the suffix was required.

<file-name>.ipk
Added in version 3.10.

Use the given file name. The .ipk suffix is used by the OPKG packaging system.



Added in version 3.10.

The Debian package epoch

No
None

Optional number that should be incremented when changing versioning schemas or fixing mistakes in the version numbers of older packages.


The Debian package version
Yes
CPACK_PACKAGE_VERSION

This variable may contain only alphanumerics (A-Za-z0-9) and the characters . + - ~ (full stop, plus, hyphen, tilde) and should start with a digit. If CPACK_DEBIAN_PACKAGE_RELEASE is not set then hyphens are not allowed.

NOTE:

For backward compatibility with CMake 3.9 and lower a failed test of this variable's content is not a hard error when both CPACK_DEBIAN_PACKAGE_RELEASE and CPACK_DEBIAN_PACKAGE_EPOCH variables are not set. An author warning is reported instead.



Added in version 3.6.

The Debian package release - Debian revision number.

No
None

This is the numbering of the DEB package itself, i.e. the version of the packaging and not the version of the content (see CPACK_DEBIAN_PACKAGE_VERSION). One may change the default value if the previous packaging was buggy and/or you want to put here a fancy Linux distro specific numbering.


The Debian package architecture
Yes
Output of dpkg --print-architecture (or i386 if dpkg is not found)

Added in version 3.6: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE variables.


Sets the Debian dependencies of this package.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_DEPENDS for component-based installations.


Added in version 3.3: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS variables.

NOTE:

If CPACK_DEBIAN_PACKAGE_SHLIBDEPS or more specifically CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS is set for this component, the discovered dependencies will be appended to CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS instead of CPACK_DEBIAN_PACKAGE_DEPENDS. If CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS is an empty string, only the automatically discovered dependencies will be set for this component.


Example:

set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)")



Added in version 3.6.

Sets inter-component dependencies if listed with CPACK_COMPONENT_<compName>_DEPENDS variables.

No
None


The Debian package maintainer
Yes
CPACK_PACKAGE_CONTACT


The Debian package description
Yes
  • CPACK_DEBIAN_<COMPONENT>_DESCRIPTION (component based installers only) if set, or CPACK_DEBIAN_PACKAGE_DESCRIPTION if set, or
  • CPACK_COMPONENT_<compName>_DESCRIPTION (component based installers only) if set, or CPACK_PACKAGE_DESCRIPTION if set, or
  • content of the file specified in CPACK_PACKAGE_DESCRIPTION_FILE if set


If after that description is not set, CPACK_PACKAGE_DESCRIPTION_SUMMARY going to be used if set. Otherwise, CPACK_PACKAGE_DESCRIPTION_SUMMARY will be added as the first line of description as defined in Debian Policy Manual.

Added in version 3.3: Per-component CPACK_COMPONENT_<compName>_DESCRIPTION variables.

Added in version 3.16: Per-component CPACK_DEBIAN_<COMPONENT>_DESCRIPTION variables.

Added in version 3.16: The CPACK_PACKAGE_DESCRIPTION_FILE variable.


Set Section control field e.g. admin, devel, doc, ...
Yes
devel

Added in version 3.5: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION variables.

See https://www.debian.org/doc/debian-policy/ch-archive.html#s-subsections


Added in version 3.7.

Deprecated since version 3.14.

The archive format used for creating the Debian package.

Yes
gnutar

Possible value is: gnutar

NOTE:

This variable previously defaulted to the paxr value, but dpkg has never supported that tar format. For backwards compatibility the paxr value will be mapped to gnutar and a deprecation message will be emitted.



Added in version 3.1.

The compression used for creating the Debian package.

Yes
gzip

Possible values are:

Lempel–Ziv–Markov chain algorithm
XZ Utils compression
bzip2 Burrows–Wheeler algorithm
GNU Gzip compression
Added in version 3.22.

Zstandard compression





Set Priority control field e.g. required, important, standard, optional, extra
Yes
optional

Added in version 3.5: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY variables.

See https://www.debian.org/doc/debian-policy/ch-archive.html#s-priorities


The URL of the web site for this package, preferably (when applicable) the site from which the original source can be obtained and any additional upstream documentation or information may be found.
No
CMAKE_PROJECT_HOMEPAGE_URL

Added in version 3.12: The CMAKE_PROJECT_HOMEPAGE_URL variable.

NOTE:

The content of this field is a simple URL without any surrounding characters such as <>.



May be set to ON in order to use dpkg-shlibdeps to generate better package dependency list.
No
  • CPACK_DEBIAN_PACKAGE_SHLIBDEPS if set or
  • OFF


NOTE:

You may need set CMAKE_INSTALL_RPATH to an appropriate value if you use this feature, because if you don't dpkg-shlibdeps may fail to find your own shared libs. See https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/RPATH-handling


NOTE:

You can also set CPACK_DEBIAN_PACKAGE_SHLIBDEPS_PRIVATE_DIRS to an appropriate value if you use this feature, in order to please dpkg-shlibdeps. However, you should only do this for private shared libraries that could not get resolved otherwise.


Added in version 3.3: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS variables.

Added in version 3.6: Correct handling of $ORIGIN in CMAKE_INSTALL_RPATH.


Added in version 3.20.

May be set to a list of directories that will be given to dpkg-shlibdeps via its -l option. These will be searched by dpkg-shlibdeps in order to find private shared library dependencies.

No
None

NOTE:

You should prefer to set CMAKE_INSTALL_RPATH to an appropriate value if you use dpkg-shlibdeps. The current option is really only needed for private shared library dependencies.



May be set when invoking cpack in order to trace debug information during the CPack DEB generator run.
No
None


Sets the Pre-Depends field of the Debian package. Like Depends, except that it also forces dpkg to complete installation of the packages named before even starting the installation of the package which declares the pre-dependency.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_PREDEPENDS for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps


Sets the Enhances field of the Debian package. Similar to Suggests but works in the opposite direction: declares that a package can enhance the functionality of another package.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_ENHANCES for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps


Sets the Breaks field of the Debian package. When a binary package (P) declares that it breaks other packages (B), dpkg will not allow the package (P) which declares Breaks be unpacked unless the packages that will be broken (B) are deconfigured first. As long as the package (P) is configured, the previously deconfigured packages (B) cannot be reconfigured again.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_BREAKS for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks


Sets the Conflicts field of the Debian package. When one binary package declares a conflict with another using a Conflicts field, dpkg will not allow them to be unpacked on the system at the same time.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_CONFLICTS for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts

NOTE:

This is a stronger restriction than Breaks, which prevents the broken package from being configured while the breaking package is in the "Unpacked" state but allows both packages to be unpacked at the same time.



Sets the Provides field of the Debian package. A virtual package is one which appears in the Provides control field of another package.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_PROVIDES for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual


Sets the Replaces field of the Debian package. Packages can declare in their control file that they should overwrite files in certain other packages, or completely replace other packages.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_REPLACES for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps


Sets the Recommends field of the Debian package. Allows packages to declare a strong, but not absolute, dependency on other packages.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_RECOMMENDS for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps


Sets the Suggests field of the Debian package. Allows packages to declare a suggested package install grouping.
No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_SUGGESTS for component-based installations.


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps


Added in version 3.6.

No
OFF

Allows to generate shlibs control file automatically. Compatibility is defined by CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY variable value.

NOTE:

Libraries are only considered if they have both library name and version set. This can be done by setting SOVERSION property with set_target_properties() command.



Added in version 3.6.

Compatibility policy for auto-generated shlibs control file.

No
=

Defines compatibility policy for auto-generated shlibs control file. Possible values: =, >=

See https://www.debian.org/doc/debian-policy/ch-sharedlibs.html#s-sharedlibs-shlibdeps


This variable allow advanced user to add custom script to the control.tar.gz. Typical usage is for conffiles, postinst, postrm, prerm.
No
None

Usage:

set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA


    "${CMAKE_CURRENT_SOURCE_DIR}/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")


Added in version 3.4: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA variables.


Added in version 3.4.

This variable indicates if the Debian policy on control files should be strictly followed.

No
FALSE

Usage:

set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE)


This overrides the permissions on the original files, following the rules set by Debian policy https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners

NOTE:

The original permissions of the files will be used in the final package unless this variable is set to TRUE. In particular, the scripts should have the proper executable flag prior to the generation of the package.



Added in version 3.5.

Sets the Source field of the binary Debian package. When the binary package name is not the same as the source package name (in particular when several components/binaries are generated from one source) the source from which the binary has been generated should be indicated with the field Source.

No
  • An empty string for non-component based installations
  • CPACK_DEBIAN_PACKAGE_SOURCE for component-based installations.


See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-source

NOTE:

This value is not interpreted. It is possible to pass an optional revision number of the referenced source package as well.



Packaging of debug information

Added in version 3.13.

Dbgsym packages contain debug symbols for debugging packaged binaries.

Dbgsym packaging has its own set of variables:

Enable generation of dbgsym .ddeb package(s).
No
OFF


NOTE:

Setting this also strips the ELF files in the generated non-dbgsym package, which results in debuginfo only being available in the dbgsym package.


NOTE:

Binaries must contain debug symbols before packaging so use either Debug or RelWithDebInfo for CMAKE_BUILD_TYPE variable value.

Additionally, if CPACK_STRIP_FILES is set, the files will be stripped before they get to the DEB generator, so will not contain debug symbols and a dbgsym package will not get built. Do not use with CPACK_STRIP_FILES.



Building Debian packages on Windows

Added in version 3.10.

To communicate UNIX file permissions from the install stage to the CPack DEB generator the cmake_mode_t NTFS alternate data stream (ADT) is used.

When a filesystem without ADT support is used only owner read/write permissions can be preserved.

Reproducible packages

Added in version 3.13.

The environment variable SOURCE_DATE_EPOCH may be set to a UNIX timestamp, defined as the number of seconds, excluding leap seconds, since 01 Jan 1970 00:00:00 UTC. If set, the CPack DEB generator will use its value for timestamps in the package.

CPack DragNDrop Generator

The DragNDrop CPack generator (macOS) creates a DMG image.

Variables specific to CPack DragNDrop generator

The following variables are specific to the DragNDrop installers built on macOS:

The volume name of the generated disk image.
CPACK_PACKAGE_FILE_NAME


The disk image format.
UDZO

Common values are UDRO (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF bzip2-compressed). Refer to hdiutil(1) for more information on other available formats.


Path to a custom .DS_Store file. This .DS_Store file can be used to specify the Finder window position/geometry and layout (such as hidden toolbars, placement of the icons etc.). This file has to be generated by the Finder (either manually or through AppleScript) using a normal folder from which the .DS_Store file can then be extracted.

Added in version 3.5.

Path to a custom AppleScript file. This AppleScript is used to generate a .DS_Store file which specifies the Finder window position/geometry and layout (such as hidden toolbars, placement of the icons etc.). By specifying a custom AppleScript there is no need to use CPACK_DMG_DS_STORE, as the .DS_Store that is generated by the AppleScript will be packaged.



Path to an image file to be used as the background. This file will be copied to .background/background.<ext>, where <ext> is the original image file extension. The background image is installed into the image before CPACK_DMG_DS_STORE_SETUP_SCRIPT is executed or CPACK_DMG_DS_STORE is installed. By default no background image is set.


Added in version 3.6.

Default behavior is to include a symlink to /Applications in the DMG. Set this option to ON to avoid adding the symlink.


Added in version 3.23.

OFF

Control whether CPACK_RESOURCE_FILE_LICENSE, if set to a non-default value, is used as the license agreement provided when mounting the DMG. If CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE is not set, cpack(1) defaults to off.

In a CMake project that uses the CPack module to generate CPackConfig.cmake, CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE must be explicitly enabled by the project to activate the SLA. See policy CMP0133.

NOTE:

This option was added in response to macOS 12.0's deprecation of the hdiutil udifrez command to make its use optional. CPack 3.22 and below always use CPACK_RESOURCE_FILE_LICENSE, if set to a non-default value, as the DMG license.



Added in version 3.5.

Directory where license and menu files for different languages are stored. Setting this causes CPack to look for a <language>.menu.txt and <language>.license.txt or <language>.license.rtf file for every language defined in CPACK_DMG_SLA_LANGUAGES. If both this variable and CPACK_RESOURCE_FILE_LICENSE are set, CPack will only look for the menu files and use the same license file for all languages. If both <language>.license.txt and <language>.license.rtf exist, the .txt file will be used.

Added in version 3.17: RTF support.


Added in version 3.5.

Languages for which a license agreement is provided when mounting the generated DMG. A menu file consists of 9 lines of text. The first line is is the name of the language itself, uppercase, in English (e.g. German). The other lines are translations of the following strings:

  • Agree
  • Disagree
  • Print
  • Save...
  • You agree to the terms of the License Agreement when you click the "Agree" button.
  • Software License Agreement
  • This text cannot be saved. The disk may be full or locked, or the file may be locked.
  • Unable to print. Make sure you have selected a printer.

For every language in this list, CPack will try to find files <language>.menu.txt and <language>.license.txt in the directory specified by the CPACK_DMG_SLA_DIR variable.


Added in version 3.17.

File name when packaging <component> as its own DMG (CPACK_COMPONENTS_GROUPING set to IGNORE).

CPACK_PACKAGE_FILE_NAME-<component>


Added in version 3.21.

HFS+

The filesystem format. Common values are APFS and HFS+. See man hdiutil for a full list of supported formats.


Path to the hdiutil(1) command used to operate on disk image files on macOS. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

Path to the SetFile(1) command used to set extended attributes on files and directories on macOS. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

Path to the Rez(1) command used to compile resources on macOS. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

CPack External Generator

Added in version 3.13.

CPack provides many generators to create packages for a variety of platforms and packaging systems. The intention is for CMake/CPack to be a complete end-to-end solution for building and packaging a software project. However, it may not always be possible to use CPack for the entire packaging process, due to either technical limitations or policies that require the use of certain tools. For this reason, CPack provides the "External" generator, which allows external packaging software to take advantage of some of the functionality provided by CPack, such as component installation and the dependency graph.

Integration with External Packaging Tools

The CPack External generator generates a .json file containing the CPack internal metadata, which gives external software information on how to package the software. External packaging software may itself invoke CPack, consume the generated metadata, install and package files as required.

Alternatively CPack can invoke an external packaging software through an optional custom CMake script in CPACK_EXTERNAL_PACKAGE_SCRIPT instead.

Staging of installation files may also optionally be taken care of by the generator when enabled through the CPACK_EXTERNAL_ENABLE_STAGING variable.

JSON Format

The JSON metadata file contains a list of CPack components and component groups, the various options passed to cpack_add_component() and cpack_add_component_group(), the dependencies between the components and component groups, and various other options passed to CPack.

The JSON's root object will always provide two fields: formatVersionMajor and formatVersionMinor, which are always integers that describe the output format of the generator. Backwards-compatible changes to the output format (for example, adding a new field that didn't exist before) cause the minor version to be incremented, and backwards-incompatible changes (for example, deleting a field or changing its meaning) cause the major version to be incremented and the minor version reset to 0. The format version is always of the format major.minor. In other words, it always has exactly two parts, separated by a period.

You can request one or more specific versions of the output format as described below with CPACK_EXTERNAL_REQUESTED_VERSIONS. The output format will have a major version that exactly matches the requested major version, and a minor version that is greater than or equal to the requested minor version. If no version is requested with CPACK_EXTERNAL_REQUESTED_VERSIONS, the latest known major version is used by default. Currently, the only supported format is 1.0, which is described below.

Version 1.0

In addition to the standard format fields, format version 1.0 provides the following fields in the root:

The components field is an object with component names as the keys and objects describing the components as the values. The component objects have the following fields:
The name of the component. This is always the same as the key in the components object.
The value of the DISPLAY_NAME field passed to cpack_add_component().
The value of the DESCRIPTION field passed to cpack_add_component().
True if HIDDEN was passed to cpack_add_component(), false if it was not.
True if REQUIRED was passed to cpack_add_component(), false if it was not.
True if DISABLED was passed to cpack_add_component(), false if it was not.
Only present if GROUP was passed to cpack_add_component(). If so, this field is a string value containing the component's group.
An array of components the component depends on. This contains the values in the DEPENDS argument passed to cpack_add_component(). If no DEPENDS argument was passed, this is an empty list.
An array of installation types the component is part of. This contains the values in the INSTALL_TYPES argument passed to cpack_add_component(). If no INSTALL_TYPES argument was passed, this is an empty list.
True if DOWNLOADED was passed to cpack_add_component(), false if it was not.
The name of the archive file passed with the ARCHIVE_FILE argument to cpack_add_component(). If no ARCHIVE_FILE argument was passed, this is an empty string.

The componentGroups field is an object with component group names as the keys and objects describing the component groups as the values. The component group objects have the following fields:
The name of the component group. This is always the same as the key in the componentGroups object.
The value of the DISPLAY_NAME field passed to cpack_add_component_group().
The value of the DESCRIPTION field passed to cpack_add_component_group().
Only present if PARENT_GROUP was passed to cpack_add_component_group(). If so, this field is a string value containing the component group's parent group.
True if EXPANDED was passed to cpack_add_component_group(), false if it was not.
True if BOLD_TITLE was passed to cpack_add_component_group(), false if it was not.
An array of names of components that are direct members of the group (components that have this group as their GROUP). Components of subgroups are not included.
An array of names of component groups that are subgroups of the group (groups that have this group as their PARENT_GROUP).

The installationTypes field is an object with installation type names as the keys and objects describing the installation types as the values. The installation type objects have the following fields:
The name of the installation type. This is always the same as the key in the installationTypes object.
The value of the DISPLAY_NAME field passed to cpack_add_install_type().
The integer index of the installation type in the list.

The projects field is an array of objects describing CMake projects which comprise the CPack project. The values in this field are derived from CPACK_INSTALL_CMAKE_PROJECTS. In most cases, this will be only a single project. The project objects have the following fields:
The project name passed to CPACK_INSTALL_CMAKE_PROJECTS.
The name of the component or component set which comprises the project.
The build directory of the CMake project. This is the directory which contains the cmake_install.cmake script.
The subdirectory to install the project into inside the CPack package.

The package name given in CPACK_PACKAGE_NAME. Only present if this option is set.
The package version given in CPACK_PACKAGE_VERSION. Only present if this option is set.
The package description file given in CPACK_PACKAGE_DESCRIPTION_FILE. Only present if this option is set.
The package description summary given in CPACK_PACKAGE_DESCRIPTION_SUMMARY. Only present if this option is set.
The build configuration given to CPack with the cpack -C option. Only present if this option is set.
The default directory permissions given in CPACK_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS. Only present if this option is set.
True if CPACK_SET_DESTDIR is true, false if it is not.
The install prefix given in CPACK_PACKAGING_INSTALL_PREFIX. Only present if CPACK_SET_DESTDIR is true.
True if CPACK_STRIP_FILES is true, false if it is not.
True if CPACK_WARN_ON_ABSOLUTE_INSTALL_DESTINATION is true, false if it is not.
True if CPACK_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION is true, false if it is not.

Variables specific to CPack External generator

This variable is used to request a specific version of the CPack External generator. It is a list of major.minor values, separated by semicolons.

If this variable is set to a non-empty value, the CPack External generator will iterate through each item in the list to search for a version that it knows how to generate. Requested versions should be listed in order of descending preference by the client software, as the first matching version in the list will be generated.

The generator knows how to generate the version if it has a versioned generator whose major version exactly matches the requested major version, and whose minor version is greater than or equal to the requested minor version. For example, if CPACK_EXTERNAL_REQUESTED_VERSIONS contains 1.0, and the CPack External generator knows how to generate 1.1, it will generate 1.1. If the generator doesn't know how to generate a version in the list, it skips the version and looks at the next one. If it doesn't know how to generate any of the requested versions, an error is thrown.

If this variable is not set, or is empty, the CPack External generator will generate the highest major and minor version that it knows how to generate.

If an invalid version is encountered in CPACK_EXTERNAL_REQUESTED_VERSIONS (one that doesn't match major.minor, where major and minor are integers), it is ignored.


This variable can be set to true to enable optional installation into a temporary staging area which can then be picked up and packaged by an external packaging tool. The top level directory used by CPack for the current packaging task is contained in CPACK_TOPLEVEL_DIRECTORY. It is automatically cleaned up on each run before packaging is initiated and can be used for custom temporary files required by the external packaging tool. It also contains the staging area CPACK_TEMPORARY_DIRECTORY into which CPack performs the installation when staging is enabled.

This variable can optionally specify the full path to a CMake script file to be run as part of the CPack invocation. It is invoked after (optional) staging took place and may run an external packaging tool. The script has access to the variables defined by the CPack config file.

Added in version 3.19.

The CPACK_EXTERNAL_PACKAGE_SCRIPT script may set this list variable to the full paths of generated package files. CPack will copy these files from the staging directory back to the top build directory and possibly produce checksum files if the CPACK_PACKAGE_CHECKSUM is set.


CPack FreeBSD Generator

Added in version 3.10.

The built in (binary) CPack FreeBSD (pkg) generator (Unix only)

Variables affecting the CPack FreeBSD (pkg) generator

•
Added in version 3.18: CPACK_ARCHIVE_THREADS


Variables specific to CPack FreeBSD (pkg) generator

The CPack FreeBSD generator may be used to create pkg(8) packages -- these may be used on FreeBSD, DragonflyBSD, NetBSD, OpenBSD, but also on Linux or OSX, depending on the installed package-management tools -- using CPack.

The CPack FreeBSD generator is a CPack generator and uses the CPACK_XXX variables used by CPack. It tries to reuse packaging information that may already be specified for Debian packages for the CPack DEB Generator. It also tries to reuse RPM packaging information when Debian does not specify.

The CPack FreeBSD generator should work on any host with libpkg installed. The packages it produces are specific to the host architecture and ABI.

The CPack FreeBSD generator sets package-metadata through CPACK_FREEBSD_XXX variables. The CPack FreeBSD generator, unlike the CPack Deb generator, does not specially support componentized packages; a single package is created from all the software artifacts created through CMake.

All of the variables can be set specifically for FreeBSD packaging in the CPackConfig file or in CMakeLists.txt, but most of them have defaults that use general settings (e.g. CMAKE_PROJECT_NAME) or Debian-specific variables when those make sense (e.g. the homepage of an upstream project is usually unchanged by the flavor of packaging). When there is no Debian information to fall back on, but the RPM packaging has it, fall back to the RPM information (e.g. package license).

Sets the package name (in the package manifest, but also affects the output filename).
Yes
•
CPACK_PACKAGE_NAME (this is always set by CPack itself, based on CMAKE_PROJECT_NAME).



Sets the package comment. This is the short description displayed by pkg(8) in standard "pkg info" output.
Yes
•
CPACK_PACKAGE_DESCRIPTION_SUMMARY (this is always set by CPack itself, if nothing else sets it explicitly).



Sets the package description. This is the long description of the package, given by "pkg info" with a specific package as argument.
Yes
  • CPACK_DEBIAN_PACKAGE_DESCRIPTION (this may be set already for Debian packaging, so it is used as a fallback).
  • CPACK_PACKAGE_DESCRIPTION_SUMMARY (this is always set by CPack itself, if nothing else sets it explicitly).
  • PROJECT_DESCRIPTION (this can be set with the DESCRIPTION parameter for project()).



The URL of the web site for this package, preferably (when applicable) the site from which the original source can be obtained and any additional upstream documentation or information may be found.
Yes
  • CPACK_PACKAGE_HOMEPAGE_URL, or if that is not set,
  • CPACK_DEBIAN_PACKAGE_HOMEPAGE (this may be set already for Debian packaging, so it is used as a fallback).


Added in version 3.12: The CPACK_PACKAGE_HOMEPAGE_URL variable.


The license, or licenses, which apply to this software package. This must be one or more license-identifiers that pkg recognizes as acceptable license identifiers (e.g. "GPLv2").
Yes
•
CPACK_RPM_PACKAGE_LICENSE



This variable is only of importance if there is more than one license. The default is "single", which is only applicable to a single license. Other acceptable values are determined by pkg -- those are "dual" or "multi" -- meaning choice (OR) or simultaneous (AND) application of the licenses.
No
single


The FreeBSD maintainer (e.g. kde@freebsd.org) of this package.
Yes
none


The origin (ports label) of this package; for packages built by CPack outside of the ports system this is of less importance. The default puts the package somewhere under misc/, as a stopgap.
Yes
misc/<package name>


The ports categories where this package lives (if it were to be built from ports). If none is set a single category is determined based on the package origin.
Yes
derived from ORIGIN


A list of package origins that should be added as package dependencies. These are in the form <category>/<packagename>, e.g. x11/libkonq. No version information needs to be provided (this is not included in the manifest).
No
empty


CPack Inno Setup Generator

Added in version 3.27.

Inno Setup is a free installer for Windows programs by Jordan Russell and Martijn Laan (https://jrsoftware.org/isinfo.php).

This documentation explains Inno Setup generator specific options.

The generator provides a lot of options like components. Unfortunately, not all features (e.g. component dependencies) are currently supported by Inno Setup and they're ignored by the generator for now.

CPack requires Inno Setup 6 or greater.

Added in version 3.30: The generator is now available on non-Windows hosts, but requires Wine to run the Inno Setup tools.

Variables specific to CPack Inno Setup generator

You can use the following variables to change the behavior of the CPack INNOSETUP generator:

General

None of the following variables is required to be set for the Inno Setup generator to work. If a variable is marked as mandatory below but not set, its default value is taken.

The variables can also contain Inno Setup constants like {app}. Please refer to the documentation of Inno Setup for more information.

If you're asked to provide the path to any file, you can always give an absolute path or in most cases the relative path from the top-level directory where all files being installed by an install() instruction reside.

CPack tries to escape quotes and other special characters for you. However, using special characters could cause problems.

The following variable simplifies the usage of Inno Setup in CMake:

Inno Setup only uses yes or no as boolean formats meanwhile CMake uses a lot of alternative formats like ON or OFF. Having this option turned on enables an automatic conversion.

Consider the following example:

set(CMAKE_INNOSETUP_SETUP_AllowNoIcons OFF)


If this option is turned on, the following line will be created in the output script: AllowNoIcons=no. Else, the following erroneous line will be created: AllowNoIcons=OFF

The conversion is enabled in every Inno Setup specific variable.

Yes
ON


Setup Specific Variables

One of x86, x64, arm64 or ia64. This variable specifies the target architecture of the installer. This also affects the Program Files folder or registry keys being used.

CPack tries to determine the correct value with a try compile (see CMAKE_SIZEOF_VOID_P), but this option can be manually specified too (especially when using ia64 or cross-platform compilation).

Yes
Either x86 or x64 depending on the results of the try-compile


If you don't want the installer to create the installation directory under Program Files, you've to specify the installation root here.

The full directory of the installation will be: ${CPACK_INNOSETUP_INSTALL_ROOT}/${CPACK_PACKAGE_INSTALL_DIRECTORY}.

Yes
{autopf}


If turned on, the installer allows the user to change the installation directory providing an extra wizard page.
Yes
ON


The initial name of the start menu folder being created.

If this variable is set to ., then no separate folder is created, application shortcuts will appear in the top-level start menu folder.

Yes
The value of CPACK_PACKAGE_NAME


A semicolon-separated list of languages you want Inno Setup to include.

Currently available: armenian, brazilianPortuguese, bulgarian, catalan, corsican, czech, danish, dutch, english, finnish, french, german, hebrew, icelandic, italian, japanese, norwegian, polish, portuguese, russian, slovak, slovenian, spanish, turkish and ukrainian. This list might differ depending on the version of Inno Setup.

Yes
english


If you don't specify a license file using CPACK_RESOURCE_FILE_LICENSE, CPack uses a file for demonstration purposes. If you want the installer to ignore license files at all, you can enable this option.
Yes
OFF


If you don't specify a readme file using CPACK_RESOURCE_FILE_README, CPack uses a file for demonstration purposes. If you want the installer to ignore readme files at all, you can enable this option. Make sure the option is disabled when using a custom readme file.
Yes
ON


Enables password protection and file encryption with the given password.
No


Enables the modern look and feel provided by Inno Setup. If this option is turned off, the classic style is used instead. Images and icon files are also affected.
Yes
OFF because of compatibility reasons


The path to a custom installer .ico file.

Use CPACK_PACKAGE_ICON to customize the bitmap file being shown in the wizard.

No


This group allows adapting any of the [Setup] section directives provided by Inno Setup where directive is its name.

Here are some examples:

set(CPACK_INNOSETUP_SETUP_WizardSmallImageFile "my_bitmap.bmp")
set(CPACK_INNOSETUP_SETUP_AllowNoIcons OFF) # This requires CPACK_INNOSETUP_USE_CMAKE_BOOL_FORMAT to be on


All of these variables have higher priority than the others. Consider the following example:

set(CPACK_INNOSETUP_SETUP_Password "admin")
set(CPACK_INNOSETUP_PASSWORD "secret")


The password will be admin at the end because CPACK_INNOSETUP_PASSWORD has less priority than CPACK_INNOSETUP_SETUP_Password.

No


File Specific Variables

Although all files being installed by an install() instruction are automatically processed and added to the installer, there are some variables to customize the installation process.

Before using executables (only .exe or .com) in shortcuts (e.g. CPACK_CREATE_DESKTOP_LINKS) or [Run] entries, you've to add the raw file name (without path and extension) to CPACK_PACKAGE_EXECUTABLES and create a start menu shortcut for them.

If you have two files with the same raw name (e.g. a/executable.exe and b/executable.com), an entry in the section is created twice. This will result in undefined behavior and is not recommended.

This variable should contain a semicolon-separated list of pairs path, instruction and can be used to customize the install command being automatically created for each file or directory.

CPack creates the following Inno Setup instruction for every file...

Source: "absolute\path\to\my_file.txt"; DestDir: "{app}"; Flags: ignoreversion


...and the following line for every directory:

Name: "{app}\my_folder"


You might want to change the destination directory or the flags of my_file.txt. Since we can also provide a relative path, the line you'd like to have, is the following:

Source: "my_file.txt"; DestDir: "{userdocs}"; Flags: ignoreversion uninsneveruninstall


You would do this by using my_file.txt as path and Source: "my_file.txt"; DestDir: "{userdocs}"; Flags: ignoreversion uninsneveruninstall as instruction.

You've to take care of the escaping problem. So the CMake command would be:

set(CPACK_INNOSETUP_CUSTOM_INSTALL_INSTRUCTIONS "my_file.txt;Source: \\\"my_file.txt\\\"\\; DestDir: \\\"{userdocs}\\\"\\; Flags: ignoreversion uninsneveruninstall")


To improve readability, you should go around the escaping problem by using CPACK_VERBATIM_VARIABLES or by placing the instruction into a separate CPack project config file.

If you customize the install instruction of a specific file, you lose the connection to its component. To go around, manually add Components: <component>. You also need to add its shortcuts and [Run] entries by yourself in a custom section, since the executable won't be found anymore by CPACK_PACKAGE_EXECUTABLES.

Here's another example (Note: You've to go around the escaping problem for the example to work):

set(CPACK_INNOSETUP_CUSTOM_INSTALL_INSTRUCTIONS


    "component1/my_folder" "Name: \"{userdocs}\\my_folder\"\; Components: component1"


    "component2/my_folder2/my_file.txt" "Source: \"component2\\my_folder2\\my_file.txt\"\; DestDir: \"{app}\\my_folder2\\my_file.txt\"\; Flags: ignoreversion uninsneveruninstall\; Components: component2")


No


This variable should contain a semicolon-separated list of pairs link, link name and can be used to add shortcuts into the start menu folder beside those of the executables (see CPACK_PACKAGE_EXECUTABLES). While link name is the label, link can be a URL or a path relative to the installation directory.

Here's an example:

set(CPACK_INNOSETUP_MENU_LINKS


    "doc/cmake-@CMake_VERSION_MAJOR@.@CMake_VERSION_MINOR@/cmake.html"


    "CMake Help" "https://cmake.org" "CMake Web Site")


No


If this option is turned on, a shortcut to the application's uninstaller is automatically added to the start menu folder.
Yes
OFF


A semicolon-separated list of executables being specified in CPACK_PACKAGE_EXECUTABLES which the user can run when the installer finishes.

They're internally added to the [Run] section.

No


Components Specific Variables

The generator supports components and also downloaded components. However, there are some features of components that aren't supported yet (especially component dependencies). These variables are ignored for now.

CPack will change a component's name in Inno Setup if it has a parent group for technical reasons. Consider using group\component as component name in Inno Setup scripts if you have the component component and its parent group group.

Here are some additional variables for components:

If you don't want the component compName to be installed under {app}, you've to specify its installation directory here.
No


This option only affects downloaded components.

If this option is turned on, the hashes of the downloaded archives are calculated during compile and download time. The installer will only proceed if they match.

Yes
ON


Compilation and Scripting Specific Variables

The filename of the Inno Setup Script Compiler command.
Yes
ISCC


A semicolon-separated list of extra command-line options for the Inno Setup Script Compiler command.

For example: /Qp;/Smysigntool=$p

Take care of the escaping problem.

No


This group allows to add custom define directives as command-line options to the Inno Setup Preprocessor command. Each entry emulates a #define public <macro> directive. Its macro is accessible from anywhere (public), so it can also be used in extra script files.

Macro names must not contain any special characters. Refer to the Inno Setup Preprocessor documentation for the detailed rules.

Consider the following example:

# The following line emulates: #define public MyMacro "Hello, World!"
set(CPACK_INNOSETUP_DEFINE_MyMacro "Hello, World!")


At this point, you can use MyMacro anywhere. For example in the following extra script:

AppComments={#emit "'My Macro' has the value: " + MyMacro}


Take care of the escaping problem.

No


A semicolon-separated list of paths to additional .iss script files to be processed.

They're internally included at the top of the output script file using a #include directive.

You can add any section in your file to extend the installer (e.g. adding additional tasks or registry keys). Prefer using CPACK_INNOSETUP_SETUP_<directive> when extending the [Setup] section.

No


A semicolon-separated list of paths to additional Pascal files to be processed.

This variable is actually the same as CPACK_INNOSETUP_EXTRA_SCRIPTS, except you don't have to add [Code] at the top of your file. Never change the current section in a code file. This will result in undefined behavior! Treat them as normal Pascal scripts instead.

Code files are included at the very bottom of the output script.

No


CPack IFW Generator

Added in version 3.1.

Configure and run the Qt Installer Framework to generate a Qt installer.

Overview

This cpack generator generates configuration and meta information for the Qt Installer Framework (QtIFW), and runs QtIFW tools to generate a Qt installer.

QtIFW provides tools and utilities to create installers for the platforms supported by Qt: Linux, Microsoft Windows, and macOS.

To make use of this generator, QtIFW needs to be installed. The CPackIFW module looks for the location of the QtIFW command-line utilities, and defines several commands to control the behavior of this generator. See Hints for Finding QtIFW.

Variables

You can use the following variables to change the behavior of the CPack IFW generator.

If not specified, QtIFW provides a default name (maintenancetool).


Added in version 3.3.

Filename for the configuration of the generated maintenance tool.

If not specified, QtIFW uses a default file name (maintenancetool.ini).


Added in version 3.3.

Set to ON if the installation path can contain non-ASCII characters. Only supported for QtIFW 2.0 and later. Older QtIFW versions will always allow non-ASCII characters.


Added in version 3.3.

Set to OFF if the installation path cannot contain space characters.

Is ON for QtIFW less 2.0 tools.


Added in version 3.23.

Set to ON if command line interface features should be disabled. It is OFF by default and will only have an effect if using QtIFW 4.0 or later.


Added in version 3.3.

Filename for a custom installer control script.


Added in version 3.7.

List of additional resources (.qrc files) to include in the installer binary. They should be specified as absolute paths and no two resource files can have the same file name.

You can use the cpack_ifw_add_package_resources() command to resolve relative paths.


Added in version 3.10.

The target binary extension.

On Linux, the name of the target binary is automatically extended with .run, if you do not specify the extension.

On Windows, the target is created as an application with the extension .exe, which is automatically added, if not supplied.

On Mac, the target is created as an DMG disk image with the extension .dmg, which is automatically added, if not supplied.


The list of remote repositories.

The default value of this variable is computed by CPack and contains all repositories added with cpack_ifw_add_repository() or updated with cpack_ifw_update_repository().


If this is ON, all components will be downloaded. If not set, the behavior is determined by whether cpack_configure_downloads() has been called with the ALL option or not.

Added in version 3.23.

A list of images to be shown on the PerformInstallationPage. These must be absolute paths and the images must be in PNG format.

This feature is available for QtIFW 4.0.0 and later.


Added in version 3.23.

Command executed after the installer is finished, if the user accepts the action. Provide the full path to the application, as found when installed. This typically means the path should begin with the QtIFW predefined variable @TargetDir@.

This feature is available for QtIFW 4.0.0 and later.


Added in version 3.23.

List of arguments passed to the program specified in CPACK_IFW_PACKAGE_RUN_PROGRAM.

This feature is available for QtIFW 4.0.0 and later.


Added in version 3.23.

  • 0 (No compression)
  • 1 (Fastest compression)
  • 3 (Fast compression)
  • 5 (Normal compression)
  • 7 (Maximum compression)
  • 9 (Ultra compression)



If this variable is not set, QtIFW will use a default compression level, which will typically be 5 (Normal compression).

NOTE:

Some formats do not support all the possible values. For example zip compression only supports values from 1 to 7.


This feature is available for QtIFW 4.2.0 and later.


Components

Resolve duplicate names when installing components with groups.

Additional prepared packages directories that will be used to resolve dependent components.

Added in version 3.10.

Additional prepared repository directories that will be used to resolve and repack dependent components.

This feature is available for QtIFW 3.1 and later.


QtIFW Tools

Added in version 3.3.

The version of the QtIFW tools that will be used. This variable is set by the CPackIFW module.


The following variables provide the locations of the QtIFW command-line tools as discovered by the CPackIFW module. These variables are cached, and may be configured if needed.

Added in version 3.19.

The path to archivegen.


The path to binarycreator.

The path to repogen.

The path to installerbase.

The path to devtool.

Hints for Finding QtIFW

Generally, the CPack IFW generator automatically finds QtIFW tools. The following (in order of precedence) can also be set to augment the locations normally searched by find_program():

Added in version 3.9.

CMake variable


Added in version 3.9.

Environment variable


CMake variable

Environment variable

NOTE:

The specified path should not contain bin at the end (for example: D:\\DevTools\\QtIFW2.0.5).


Other Settings

Online installer

By default, this generator generates an offline installer. This means that all packaged files are fully contained in the installer executable.

In contrast, an online installer will download some or all components from a remote server.

The DOWNLOADED option in the cpack_add_component() command specifies that a component is to be downloaded. Alternatively, the ALL option in the cpack_configure_downloads() command specifies that all components are to be be downloaded.

The cpack_ifw_add_repository() command and the CPACK_IFW_DOWNLOAD_ALL variable allow for more specific configuration.

When there are online components, CPack will write them to archive files. The help page of the CPackComponent module, especially the section on the cpack_configure_downloads() function, explains how to make these files accessible from a download URL.

Internationalization

Added in version 3.9.

Some variables and command arguments support internationalization via CMake script. This is an optional feature.

Installers created by QtIFW tools have built-in support for internationalization and many phrases are localized to many languages, but this does not apply to the description of your components and groups.

Localization of the description of your components and groups is useful for users of your installers.

A localized variable or argument can contain a single default value, and after that a set of pairs with the name of the locale and the localized value.

For example:

set(LOCALIZABLE_VARIABLE "Default value"


  en "English value"


  en_US "American value"


  en_GB "Great Britain value"


  )

Specify an executable to add an option to run on the finish page of the NSIS installer.

Specify links in [application] menu. This should contain a list of pair link link name. The link may be a URL or a path relative to installation prefix. Like:

set(CPACK_NSIS_MENU_LINKS


    "doc/cmake-@CMake_VERSION_MAJOR@.@CMake_VERSION_MINOR@/cmake.html"


    "CMake Help" "https://cmake.org" "CMake Web Site")

If set, updates the text at the bottom of the install window. To set the string to blank, use a space (" ").


Added in version 3.20.

If set, trim down the size of the control to the size of the branding text string. Allowed values for this variable are LEFT, CENTER or RIGHT. If not specified, the default behavior is LEFT.


Added in version 3.21.

If set, specify the name of the NSIS executable. Default is makensis.


Added in version 3.22.

If set, do not display the page containing the license during installation.


Added in version 3.25.

This variable is a semicolon-separated list of arguments to prepend to the nsis script to run. If the arguments do not start with a / or a -, it will add one automatically to the corresponding arguments. The command that will be run is:

makensis.exe <preArgs>... "nsisFileName.nsi" <postArgs>...


where <preArgs>... is constructed from CPACK_NSIS_EXECUTABLE_PRE_ARGUMENTS and <postArgs>... is constructed from CPACK_NSIS_EXECUTABLE_POST_ARGUMENTS.


Added in version 3.25.

This variable is a semicolon-separated list of arguments to append to the nsis script to run. If the arguments do not start with a / or a -, it will add one automatically to the corresponding arguments. The command that will be run is:

makensis.exe <preArgs>... "nsisFileName.nsi" <postArgs>...


where <preArgs>... is constructed from CPACK_NSIS_EXECUTABLE_PRE_ARGUMENTS and <postArgs>... is constructed from CPACK_NSIS_EXECUTABLE_POST_ARGUMENTS.


CPack NuGet Generator

Added in version 3.12.

When build a NuGet package there is no direct way to control an output filename due a lack of the corresponding CLI option of NuGet, so there is no CPACK_NUGET_PACKAGE_FILE_NAME variable. To form the output filename NuGet uses the package name and the version according to its built-in rules.

Also, be aware that including a top level directory (CPACK_INCLUDE_TOPLEVEL_DIRECTORY) is ignored by this generator.

Variables specific to CPack NuGet generator

The CPack NuGet generator may be used to create NuGet packages using CPack. The CPack NuGet generator is a CPack generator thus it uses the CPACK_XXX variables used by CPack.

The CPack NuGet generator has specific features which are controlled by the specifics CPACK_NUGET_XXX variables. In the "one per group" mode (see CPACK_COMPONENTS_GROUPING), <compName> placeholder in the variables below would contain a group name (uppercased and turned into a "C" identifier).

CPack PackageMaker Generator

Removed. This once generated PackageMaker installers, but the generator has been removed since CMake 3.24. Xcode no longer distributes the PackageMaker tools. Use the CPack productbuild Generator instead.

CPack productbuild Generator

Added in version 3.7.

productbuild CPack generator (macOS).

Variables specific to CPack productbuild generator

The following variable is specific to installers built on Mac macOS using ProductBuild:

Path to the productbuild(1) command used to generate a product archive for the macOS Installer or Mac App Store. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

Added in version 3.23.

Set the unique (non-localized) product identifier to be associated with the product (i.e., com.kitware.cmake). Any component product names will be appended to this value.


Added in version 3.8.

Adds a digital signature to the resulting package.


Added in version 3.8.

Specify a specific keychain to search for the signing identity.


Path to the pkgbuild(1) command used to generate an macOS component package on macOS. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

Added in version 3.8.

Adds a digital signature to the resulting package.


Added in version 3.8.

Specify a specific keychain to search for the signing identity.


Full path to a file that will be used as the preinstall script for the named <COMP> component's package, where <COMP> is the uppercased component name. No preinstall script is added if this variable is not defined for a given component.

Full path to a file that will be used as the postinstall script for the named <COMP> component's package, where <COMP> is the uppercased component name. No postinstall script is added if this variable is not defined for a given component.

Added in version 3.9.

If specified the productbuild generator copies files from this directory (including subdirectories) to the Resources directory. This is done before the CPACK_RESOURCE_FILE_WELCOME, CPACK_RESOURCE_FILE_README, and CPACK_RESOURCE_FILE_LICENSE files are copied.


Added in version 3.23.

This option enables more granular control over where the product may be installed. When it is set to true (see policy CMP0161), a domains element of the following form will be added to the productbuild Distribution XML:

<domains enable_anywhere="true" enable_currentUserHome="false" enable_localSystem="true"/>


The default values are as shown above, but can be overridden with CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE, CPACK_PRODUCTBUILD_DOMAINS_USER, and CPACK_PRODUCTBUILD_DOMAINS_ROOT.


Added in version 3.23.

May be used to override the enable_anywhere attribute in the domains element of the Distribution XML. When set to true, the product can be installed at the root of any volume, including non-system volumes.

CPACK_PRODUCTBUILD_DOMAINS must be set to true for this variable to have any effect.


Added in version 3.23.

May be used to override the enable_currentUserHome attribute in the domains element of the Distribution XML. When set to true, the product can be installed into the current user's home directory. Note that when installing into the user's home directory, the following additional requirements will apply:

  • The installer may not write outside the user's home directory.
  • The install will be performed as the current user rather than as root. This may have ramifications for CPACK_PREFLIGHT_<COMP>_SCRIPT and CPACK_POSTFLIGHT_<COMP>_SCRIPT.
  • Administrative privileges will not be needed to perform the install.

CPACK_PRODUCTBUILD_DOMAINS must be set to true for this variable to have any effect.


Added in version 3.23.

May be used to override the enable_localSystem attribute in the domains element of the Distribution XML. When set to true, the product can be installed in the root directory. This should normally be set to true unless the product should only be installed to the user's home directory.

CPACK_PRODUCTBUILD_DOMAINS must be set to true for this variable to have any effect.


Background Image

Added in version 3.17.

This group of variables controls the background image of the generated installer.

Adds a background to Distribution XML if specified. The value contains the path to image in Resources directory.

Adds an alignment attribute to the background in Distribution XML. Refer to Apple documentation for valid values.

Adds a scaling attribute to the background in Distribution XML. Refer to Apple documentation for valid values.

Adds a mime-type attribute to the background in Distribution XML. The option contains MIME type of an image.

Adds an uti attribute to the background in Distribution XML. The option contains UTI type of an image.

Adds a background for the Dark Aqua theme to Distribution XML if specified. The value contains the path to image in Resources directory.

Does the same as CPACK_PRODUCTBUILD_BACKGROUND_ALIGNMENT option, but for the dark theme.

Does the same as CPACK_PRODUCTBUILD_BACKGROUND_SCALING option, but for the dark theme.

Does the same as CPACK_PRODUCTBUILD_BACKGROUND_MIME_TYPE option, but for the dark theme.

Does the same as CPACK_PRODUCTBUILD_BACKGROUND_UTI option, but for the dark theme.

Distribution XML Template

CPack uses a template file to generate the distribution.dist file used internally by this package generator. Ordinarily, CMake provides the template file, but projects may supply their own by placing a file called CPack.distribution.dist.in in one of the directories listed in the CMAKE_MODULE_PATH variable. CPack will then pick up the project's template file instead of using its own.

The distribution.dist file is generated by performing substitutions similar to the configure_file() command. Any variable set when CPack runs will be available for substitution using the usual @...@ form. The following variables are also set internally and made available for substitution:

Same as CPACK_RESOURCE_FILE_LICENSE except without the path. The named file will be available in the same directory as the generated distribution.dist file.
Same as CPACK_RESOURCE_FILE_README except without the path. The named file will be available in the same directory as the generated distribution.dist file.
Same as CPACK_RESOURCE_FILE_WELCOME except without the path. The named file will be available in the same directory as the generated distribution.dist file.
Added in version 3.23.

This contains all the XML elements that specify installer-wide options (including domain details), default backgrounds and the choices outline.

Deprecated since version 3.23.

This contains only the XML elements that specify the default backgrounds and the choices outline. It does not include the installer-wide options or any domain details. Use CPACK_APPLE_PKG_INSTALLER_CONTENT instead.


CPack RPM Generator

The built in (binary) CPack RPM generator (Unix only)

Variables specific to CPack RPM generator

The CPack RPM generator may be used to create RPM packages using CPack. The CPack RPM generator is a CPack generator thus it uses the CPACK_XXX variables used by CPack.

The CPack RPM generator has specific features which are controlled by the specifics CPACK_RPM_XXX variables.

CPACK_RPM_<COMPONENT>_XXXX variables may be used in order to have component-specific values. Note however that <COMPONENT> refers to the grouping name written in upper case. It may be either a component name or a component GROUP name. Usually, those variables correspond to RPM spec file entities. One may find information about spec files here https://rpm.org/documentation.

Changed in version 3.6: <COMPONENT> part of variables is preferred to be in upper case (e.g. if component is named foo then use CPACK_RPM_FOO_XXXX variable name format) as is with other CPACK_<COMPONENT>_XXXX variables. For the purposes of back compatibility (CMake/CPack version 3.5 and lower) support for same cased component (e.g. fOo would be used as CPACK_RPM_fOo_XXXX) is still supported for variables defined in older versions of CMake/CPack but is not guaranteed for variables that will be added in the future. For the sake of back compatibility same cased component variables also override upper cased versions where both are present.

Here are some CPack RPM generator wiki resources that are here for historic reasons and are no longer maintained but may still prove useful:




List of CPack RPM generator specific variables:

Enable component packaging for CPack RPM generator
No
OFF

If enabled (ON) multiple packages are generated. By default a single package containing files of all components is generated.


The RPM package summary.
Yes
CPACK_PACKAGE_DESCRIPTION_SUMMARY

Added in version 3.2: Per-component CPACK_RPM_<component>_PACKAGE_SUMMARY variables.


The RPM package name.
Yes
CPACK_PACKAGE_NAME

Added in version 3.5: Per-component CPACK_RPM_<component>_PACKAGE_NAME variables.


Added in version 3.6.

Package file name.

Yes
<CPACK_PACKAGE_FILE_NAME>[-<component>].rpm with spaces replaced by '-'

This may be set to:

Tell rpmbuild to automatically generate the package file name.
<file-name>[.rpm]
Use the given file name.

Changed in version 3.29: The .rpm suffix will be automatically added if missing. Previously the suffix was required.


NOTE:

By using user provided spec file, rpm macro extensions such as for generating debuginfo packages or by simply using multiple components more than one rpm file may be generated, either from a single spec file or from multiple spec files (each component execution produces its own spec file). In such cases duplicate file names may occur as a result of this variable setting or spec file content structure. Duplicate files get overwritten and it is up to the packager to set the variables in a manner that will prevent such errors.



Added in version 3.8.

Main component that is packaged without component suffix.

No

This variable can be set to any component or group name so that component or group rpm package is generated without component suffix in filename and package name.


Added in version 3.10.

The RPM package epoch

No

Optional number that should be incremented when changing versioning schemas or fixing mistakes in the version numbers of older packages.


The RPM package version.
Yes
CPACK_PACKAGE_VERSION


The RPM package architecture.
Yes

This may be set to noarch if you know you are building a noarch package.

Added in version 3.3: Per-component CPACK_RPM_<component>_PACKAGE_ARCHITECTURE variables.


The RPM package release.
Yes
1

This is the numbering of the RPM package itself, i.e. the version of the packaging and not the version of the content (see CPACK_RPM_PACKAGE_VERSION). One may change the default value if the previous packaging was buggy and/or you want to put here a fancy Linux distro specific numbering.


NOTE:

This is the string that goes into the RPM Release: field. Some distros (e.g. Fedora, CentOS) require 1%{?dist} format and not just a number. %{?dist} part can be added by setting CPACK_RPM_PACKAGE_RELEASE_DIST.


Added in version 3.6.

The dist tag that is added RPM Release: field.

No
OFF

This is the reported %{dist} tag from the current distribution or empty %{dist} if RPM macro is not set. If this variable is set then RPM Release: field value is set to ${CPACK_RPM_PACKAGE_RELEASE}%{?dist}.


The RPM package license policy.
Yes
"unknown"


The RPM package group.
Yes
"unknown"

Added in version 3.5: Per-component CPACK_RPM_<component>_PACKAGE_GROUP variables.


The RPM package vendor.
Yes
CPACK_PACKAGE_VENDOR if set or "unknown"


The projects URL.
No
CMAKE_PROJECT_HOMEPAGE_URL

Added in version 3.12: The CMAKE_PROJECT_HOMEPAGE_URL variable.


RPM package description.
Yes
  • CPACK_COMPONENT_<compName>_DESCRIPTION (component based installers only) if set,
  • CPACK_PACKAGE_DESCRIPTION_FILE if set, or
  • no package description available


Added in version 3.2: Per-component CPACK_RPM_<component>_PACKAGE_DESCRIPTION variables.


RPM compression type.
No
(system default)

May be used to override RPM compression type to be used to build the RPM. For example some Linux distribution now default to lzma or xz compression whereas older cannot use such RPM. Using this one can enforce compression type to be used.

Possible values are:

Lempel–Ziv–Markov chain algorithm
XZ Utils compression
bzip2 Burrows–Wheeler algorithm
GNU Gzip compression




RPM spec autoreq field.
No

May be used to enable (1, yes) or disable (0, no) automatic shared libraries dependency detection. Dependencies are added to requires list.

NOTE:

By default automatic dependency detection is enabled by rpm generator.



RPM spec autoprov field.
No

May be used to enable (1, yes) or disable (0, no) automatic listing of shared libraries that are provided by the package. Shared libraries are added to provides list.

NOTE:

By default automatic provides detection is enabled by rpm generator.



RPM spec autoreqprov field.
No

Variable enables/disables autoreq and autoprov at the same time. See CPACK_RPM_PACKAGE_AUTOREQ and CPACK_RPM_PACKAGE_AUTOPROV for more details.

NOTE:

By default automatic detection feature is enabled by rpm.



RPM spec requires field.
No

May be used to set RPM dependencies (requires). Note that you must enclose the complete requires string between quotes, for example:

set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8")


The required package list of an RPM file could be printed with:

rpm -qp --requires file.rpm



RPM spec conflicts field.
No

May be used to set negative RPM dependencies (conflicts). Note that you must enclose the complete requires string between quotes, for example:

set(CPACK_RPM_PACKAGE_CONFLICTS "libxml2")


The conflicting package list of an RPM file could be printed with:

rpm -qp --conflicts file.rpm



Added in version 3.2.

RPM spec requires(pre) field.

No

May be used to set RPM preinstall dependencies (requires(pre)). Note that you must enclose the complete requires string between quotes, for example:

set(CPACK_RPM_PACKAGE_REQUIRES_PRE "shadow-utils, initscripts")



Added in version 3.2.

RPM spec requires(post) field.

No

May be used to set RPM postinstall dependencies (requires(post)). Note that you must enclose the complete requires string between quotes, for example:

set(CPACK_RPM_PACKAGE_REQUIRES_POST "shadow-utils, initscripts")



Added in version 3.2.

RPM spec requires(postun) field.

No

May be used to set RPM postuninstall dependencies (requires(postun)). Note that you must enclose the complete requires string between quotes, for example:

set(CPACK_RPM_PACKAGE_REQUIRES_POSTUN "shadow-utils, initscripts")



Added in version 3.2.

RPM spec requires(preun) field.

No

May be used to set RPM preuninstall dependencies (requires(preun)). Note that you must enclose the complete requires string between quotes, for example:

set(CPACK_RPM_PACKAGE_REQUIRES_PREUN "shadow-utils, initscripts")



RPM spec suggest field.
No

May be used to set weak RPM dependencies (suggests). If rpmbuild doesn't support the Suggests tag, CPack will emit a warning and ignore this variable. Note that you must enclose the complete requires string between quotes.


RPM spec provides field.
No

May be used to set RPM dependencies (provides). The provided package list of an RPM file could be printed with:

rpm -qp --provides file.rpm



RPM spec obsoletes field.
No

May be used to set RPM packages that are obsoleted by this one.


build a relocatable RPM.
No
CPACK_PACKAGE_RELOCATABLE

If this variable is set to TRUE or ON, the CPack RPM generator will try to build a relocatable RPM package. A relocatable RPM may be installed using:

rpm --prefix or --relocate


in order to install it at an alternate place see rpm(8). Note that currently this may fail if CPACK_SET_DESTDIR is set to ON. If CPACK_SET_DESTDIR is set then you will get a warning message but if there is file installed with absolute path you'll get unexpected behavior.


Deprecated since version 2.8.12: Use CPACK_RPM_SPEC_MORE_DEFINE instead.

No

May be used to override the __spec_install_post section within the generated spec file. This affects the install step during package creation, not during package installation. For adding operations to be performed during package installation, use CPACK_RPM_POST_INSTALL_SCRIPT_FILE instead.


RPM extended spec definitions lines.
No

May be used to add any %define lines to the generated spec file. An example of its use is to prevent stripping of executables (but note that this may also disable other default post install processing):

set(CPACK_RPM_SPEC_MORE_DEFINE "%define __spec_install_post /bin/true")



Toggle CPack RPM generator debug output.
No

May be set when invoking cpack in order to trace debug information during CPack RPM run. For example you may launch CPack like this:

cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM



A user provided spec file.
No

May be set by the user in order to specify a USER binary spec file to be used by the CPack RPM generator instead of generating the file. The specified file will be processed by configure_file( @ONLY).


Spec file template.
No

If set CPack will generate a template for USER specified binary spec file and stop with an error. For example launch CPack like this:

cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM


The user may then use this file in order to hand-craft is own binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.


Path to file containing pre install/uninstall/transaction script.
No

May be used to embed a pre installation/uninstallation/transaction script in the spec file. The referred script file (or both) will be read and directly put after the %pre or %preun section If CPACK_RPM_COMPONENT_INSTALL is set to ON the install/uninstall/transaction script for each component can be overridden with CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE, CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE, and CPACK_RPM_<COMPONENT>_PRE_TRANS_SCRIPT_FILE One may verify which scriptlet has been included with:

rpm -qp --scripts  package.rpm


Added in version 3.18: The CPACK_RPM_PRE_TRANS_SCRIPT_FILE variable.


Path to file containing post install/uninstall/transaction script.
No

May be used to embed a post installation/uninstallation/transaction script in the spec file. The referred script file (or both) will be read and directly put after the %post or %postun section. If CPACK_RPM_COMPONENT_INSTALL is set to ON the install/uninstall/transaction script for each component can be overridden with CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE, CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE, and CPACK_RPM_<COMPONENT>_POST_TRANS_SCRIPT_FILE One may verify which scriptlet has been included with:

rpm -qp --scripts  package.rpm


Added in version 3.18: The CPACK_RPM_POST_TRANS_SCRIPT_FILE variable.


No

May be used to explicitly specify %(<directive>) file line in the spec file. Like %config(noreplace) or any other directive that be found in the %files section. Since the CPack RPM generator is generating the list of files (and directories) the user specified files of the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list. If referring to directories do not add a trailing slash.

Added in version 3.8: You can have multiple directives per line, as in %attr(600,root,root) %config(noreplace).


RPM changelog file.
No

May be used to embed a changelog in the spec file. The referred file will be read and directly put after the %changelog section.


list of path to be excluded.
No
  • /etc
  • /etc/init.d
  • /usr
  • /usr/bin
  • /usr/include
  • /usr/lib
  • /usr/libx32
  • /usr/lib64
  • /usr/share
  • /usr/share/aclocal

May be used to exclude path (directories or files) from the auto-generated list of paths discovered by CPack RPM. The default value contains a reasonable set of values if the variable is not defined by the user. If the variable is defined by the user then the CPack RPM generator will NOT any of the default path. If you want to add some path to the default list then you can use CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable.

Added in version 3.10: Added /usr/share/aclocal to the default list of excludes.


additional list of path to be excluded.
No

May be used to add more exclude path (directories or files) from the initial default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.


Added in version 3.2.

Packages relocation paths list.

No

May be used to specify more than one relocation path per relocatable RPM. Variable contains a list of relocation paths that if relative are prefixed by the value of CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX or by the value of CPACK_PACKAGING_INSTALL_PREFIX if the component version is not provided. Variable is not component based as its content can be used to set a different path prefix for e.g. binary dir and documentation dir at the same time. Only prefixes that are required by a certain component are added to that component - component must contain at least one file/directory/symbolic link with CPACK_RPM_RELOCATION_PATHS prefix for a certain relocation path to be added. Package will not contain any relocation paths if there are no files/directories/symbolic links on any of the provided prefix locations. Packages that either do not contain any relocation paths or contain files/directories/symbolic links that are outside relocation paths print out an AUTHOR_WARNING that RPM will be partially relocatable.


Added in version 3.2.

Per component relocation path install prefix.

No
CPACK_PACKAGING_INSTALL_PREFIX

May be used to set per component CPACK_PACKAGING_INSTALL_PREFIX for relocatable RPM packages.


Added in version 3.3.

Removal of default install prefix from relocation paths list.

No
CPACK_PACKAGING_INSTALL_PREFIX or CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX are treated as one of relocation paths

May be used to remove CPACK_PACKAGING_INSTALL_PREFIX and CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX from relocatable RPM prefix paths.


Added in version 3.3.

No
  • /usr/man/man.*
  • /usr/man/.*/man.*
  • /usr/info.*
  • /usr/share/man/man.*
  • /usr/share/man/.*/man.*
  • /usr/share/info.*
  • /usr/kerberos/man.*
  • /usr/X11R6/man/man.*
  • /usr/lib/perl5/man/man.*
  • /usr/share/doc/.*/man/man.*
  • /usr/lib/.*/man/man.*



May be used to set additional man dirs that could potentially be compressed by brp-compress RPM macro. Variable content must be a list of regular expressions that point to directories containing man files or to man files directly. Note that in order to compress man pages a path must also be present in brp-compress RPM script and that brp-compress script must be added to RPM configuration by the operating system.


Added in version 3.6.

default user ownership of RPM content

No
root

Value should be user name and not UID. Note that <compName> must be in upper-case.


Added in version 3.6.

default group ownership of RPM content

No
root

Value should be group name and not GID. Note that <compName> must be in upper-case.


Added in version 3.6.

default permissions used for packaged files

No
(system default)

Accepted values are lists with PERMISSIONS. Valid permissions are:

  • OWNER_READ
  • OWNER_WRITE
  • OWNER_EXECUTE
  • GROUP_READ
  • GROUP_WRITE
  • GROUP_EXECUTE
  • WORLD_READ
  • WORLD_WRITE
  • WORLD_EXECUTE

Note that <compName> must be in upper-case.


Added in version 3.6.

default permissions used for packaged directories

No
(system default)

Accepted values are lists with PERMISSIONS. Valid permissions are the same as for CPACK_RPM_DEFAULT_FILE_PERMISSIONS. Note that <compName> must be in upper-case.


Added in version 3.11.

force execute permissions on programs and shared libraries

No
(system default)

Force set owner, group and world execute permissions on programs and shared libraries. This can be used for creating valid rpm packages on systems such as Debian where shared libraries do not have execute permissions set.


NOTE:

Programs and shared libraries without execute permissions are ignored during separation of debug symbols from the binary for debuginfo packages.


Added in version 3.3.

The CPack RPM generator supports packaging of symbolic links:

execute_process(COMMAND ${CMAKE_COMMAND}


  -E create_symlink <relative_path_location> <symlink_name>)
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name>


  DESTINATION <symlink_location> COMPONENT libraries)


Symbolic links will be optimized (paths will be shortened if possible) before being added to the package or if multiple relocation paths are detected, a post install symlink relocation script will be generated.

Symbolic links may point to locations that are not packaged by the same package (either a different component or even not packaged at all) but those locations will be treated as if they were a part of the package while determining if symlink should be either created or present in a post install script - depending on relocation paths.

Changed in version 3.6: Symbolic links that point to locations outside packaging path produce a warning and are treated as non relocatable permanent symbolic links. Previous versions of CMake produced an error in this case.

Currently there are a few limitations though:

  • For component based packaging component interdependency is not checked when processing symbolic links. Symbolic links pointing to content of a different component are treated the same way as if pointing to location that will not be packaged.
  • Symbolic links pointing to a location through one or more intermediate symbolic links will not be handled differently - if the intermediate symbolic link(s) is also on a relocatable path, relocating it during package installation may cause initial symbolic link to point to an invalid location.

Packaging of debug information

Added in version 3.7.

Debuginfo packages contain debug symbols and sources for debugging packaged binaries.

Debuginfo RPM packaging has its own set of variables:

Enable generation of debuginfo RPM package(s).
No
OFF


NOTE:

Binaries must contain debug symbols before packaging so use either Debug or RelWithDebInfo for CMAKE_BUILD_TYPE variable value.

Additionally, if CPACK_STRIP_FILES is set, the files will be stripped before they get to the RPM generator, so will not contain debug symbols and a debuginfo package will not get built. Do not use with CPACK_STRIP_FILES.



NOTE:

Packages generated from packages without binary files, with binary files but without execute permissions or without debug symbols will cause packaging termination.


Provides locations of root directories of source files from which binaries were built.
Yes if CPACK_RPM_DEBUGINFO_PACKAGE is set


NOTE:

For CMake project CPACK_BUILD_SOURCE_DIRS is set by default to point to CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR paths.


NOTE:

Sources with path prefixes that do not fall under any location provided with CPACK_BUILD_SOURCE_DIRS will not be present in debuginfo package.


Prefix of location where sources will be placed during package installation.
Yes if CPACK_RPM_DEBUGINFO_PACKAGE is set
/usr/src/debug/${CPACK_PACKAGE_FILE_NAME} and for component packaging /usr/src/debug/${CPACK_PACKAGE_FILE_NAME}-<component>


NOTE:

Each source path prefix is additionally suffixed by src_<index> where index is index of the path used from CPACK_BUILD_SOURCE_DIRS variable. This produces ${CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX}/src_<index> replacement path. Limitation is that replaced path part must be shorter or of equal length than the length of its replacement. If that is not the case either CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX variable has to be set to a shorter path or source directories must be placed on a longer path.


Directories containing sources that should be excluded from debuginfo packages.
No
  • /usr
  • /usr/src
  • /usr/src/debug



Listed paths are owned by other RPM packages and should therefore not be deleted on debuginfo package uninstallation.


Paths that should be appended to CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS for exclusion.
No


Added in version 3.8.

Create a single debuginfo package even if components packaging is set.

No
OFF

When this variable is enabled it produces a single debuginfo package even if component packaging is enabled.

When using this feature in combination with components packaging and there is more than one component this variable requires CPACK_RPM_MAIN_COMPONENT to be set.


NOTE:

If none of the CPACK_RPM_<component>_DEBUGINFO_PACKAGE variables is set then CPACK_RPM_DEBUGINFO_PACKAGE is automatically set to ON when CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE is set.


Added in version 3.9.

Debuginfo package file name.

No
rpmbuild tool generated package file name

Alternatively provided debuginfo package file name must end with .rpm suffix and should differ from file names of other generated packages.

Variable may contain @cpack_component@ placeholder which will be replaced by component name if component packaging is enabled otherwise it deletes the placeholder.

Setting the variable to RPM-DEFAULT may be used to explicitly set filename generation to default.


NOTE:

CPACK_RPM_FILE_NAME also supports rpmbuild tool generated package file name - disabled by default but can be enabled by setting the variable to RPM-DEFAULT.


Packaging of sources (SRPM)

Added in version 3.7.

SRPM packaging is enabled by setting CPACK_RPM_PACKAGE_SOURCES variable while usually using CPACK_INSTALLED_DIRECTORIES variable to provide directory containing CMakeLists.txt and source files.

For CMake projects SRPM package would be produced by executing:

cpack -G RPM --config ./CPackSourceConfig.cmake


NOTE:

Produced SRPM package is expected to be built with cmake(1) executable and packaged with cpack(1) executable so CMakeLists.txt has to be located in root source directory and must be able to generate binary rpm packages by executing cpack -G command. The two executables as well as rpmbuild must also be present when generating binary rpm packages from the produced SRPM package.


Once the SRPM package is generated it can be used to generate binary packages by creating a directory structure for rpm generation and executing rpmbuild tool:

mkdir -p build_dir/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
rpmbuild --define "_topdir <path_to_build_dir>" --rebuild <SRPM_file_name>


Generated packages will be located in build_dir/RPMS directory or its sub directories.

NOTE:

SRPM package internally uses CPack/RPM generator to generate binary packages so CMakeScripts.txt can decide during the SRPM to binary rpm generation step what content the package(s) should have as well as how they should be packaged (monolithic or components). CMake can decide this for e.g. by reading environment variables set by the package manager before starting the process of generating binary rpm packages. This way a single SRPM package can be used to produce different binary rpm packages on different platforms depending on the platform's packaging rules.


Source RPM packaging has its own set of variables:

Should the content be packaged as a source rpm (default is binary rpm).
No
OFF


NOTE:

For cmake projects CPACK_RPM_PACKAGE_SOURCES variable is set to OFF in CPackConfig.cmake and ON in CPackSourceConfig.cmake generated files.


Additional command-line parameters provided to cmake(1) executable.
No


Packaging install prefix that would be provided in CPACK_PACKAGING_INSTALL_PREFIX variable for producing binary RPM packages.
Yes
/


List of source rpm build dependencies.
No

May be used to set source RPM build dependencies (BuildRequires). Note that you must enclose the complete build requirements string between quotes, for example:

set(CPACK_RPM_BUILDREQUIRES "python >= 2.5.0, cmake >= 2.8")



Added in version 3.22.

No

May be used to keep the dependency generator from scanning specific files or directories for dependencies. Note that you can use a regular expression that matches all of the directories or files, for example:

set(CPACK_RPM_REQUIRES_EXCLUDE_FROM "bin/libqsqloci.*\\.so.*")



CPack WIX Generator

Use the WiX Toolset to produce a Windows Installer .msi database.

Added in version 3.7: The CPACK_COMPONENT_<compName>_DISABLED variable is now supported.

WiX Toolsets

CPack selects one of the following variants of the WiX Toolset based on the CPACK_WIX_VERSION variable:

  • WiX .NET Tools
  • WiX Toolset v3

WiX .NET Tools

Packaging is performed using the following tools:

Build WiX source files directly into a Windows Installer .msi database.

Invocations may be customized using tool-specific variables:

  • CPACK_WIX_BUILD_EXTENSIONS
  • CPACK_WIX_BUILD_EXTRA_FLAGS


WiX extensions must be named with the form WixToolset.<Name>.wixext.

CPack expects the wix .NET tool to be available for command-line use with any required WiX extensions already installed. Be sure the wix version is compatible with CPACK_WIX_VERSION, and that WiX extension versions match the wix tool version. For example:

1.
Install the wix command-line tool using dotnet.

To install wix globally for the current user: 

dotnet tool install --global wix --version 4.0.4


This places wix.exe in %USERPROFILE%\.dotnet\tools and adds the directory to the current user's PATH environment variable.

Or, to install wix in a specific path, e.g., in c:\WiX:

dotnet tool install --tool-path c:\WiX wix --version 4.0.4


This places wix.exe in c:\WiX, but does not add it to the current user's PATH environment variable. The WIX environment variable may be set to tell CPack where to find the tool, e.g., set WIX=c:\WiX.



2.
Add the WiX UI extension, needed by CPack's default WiX template:

wix extension add --global WixToolset.UI.wixext/4.0.4


Extensions added globally are stored in %USERPROFILE%\.wix, or if the WIX_EXTENSIONS environment variable is set, in %WIX_EXTENSIONS%\.wix.



WiX Toolset v3

Packaging is performed using the following tools:

Compiles WiX source files into .wixobj files.

Invocations may be customized using tool-specific variables:

  • CPACK_WIX_CANDLE_EXTENSIONS
  • CPACK_WIX_CANDLE_EXTRA_FLAGS

Links .wixobj files into a Windows Installer .msi database.

Invocations may be customized using tool-specific variables:

  • CPACK_WIX_LIGHT_EXTENSIONS
  • CPACK_WIX_LIGHT_EXTRA_FLAGS


CPack invokes both tools as needed. Intermediate .wixobj files are considered implementation details.

WiX extensions must be named with the form Wix<Name>Extension.

CPack expects the above tools to be available for command-line use via the PATH. Or, if the WIX environment variable is set, CPack looks for the tools in %WIX% and %WIX%\bin.

Variables specific to CPack WIX generator

The following variables are specific to the installers built on Windows using WiX.

Added in version 3.30.

Specify the version of WiX Toolset for which the configuration is written. The value must be one of

4
Package using WiX .NET Tools.
3
Package using WiX Toolset v3. This is the default.


Upgrade GUID (Product/@UpgradeCode)

Will be automatically generated unless explicitly provided.

It should be explicitly set to a constant generated globally unique identifier (GUID) to allow your installers to replace existing installations that use the same GUID.

You may for example explicitly set this variable in your CMakeLists.txt to the value that has been generated per default. You should not use GUIDs that you did not generate yourself or which may belong to other projects.

A GUID shall have the following fixed length syntax:

XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX


(each X represents an uppercase hexadecimal digit)


Product GUID (Product/@Id)

Will be automatically generated unless explicitly provided.

If explicitly provided this will set the Product Id of your installer.

The installer will abort if it detects a pre-existing installation that uses the same GUID.

The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.


RTF License File

If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.

If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly converted to RTF by the WIX Generator. The expected encoding of the .txt file is UTF-8.

With CPACK_WIX_LICENSE_RTF you can override the license file used by the WIX Generator in case CPACK_RESOURCE_FILE_LICENSE is in an unsupported format or the .txt -> .rtf conversion does not work as expected.


The Icon shown next to the program name in Add/Remove programs.

If set, this icon is used in place of the default icon.


Specify the WiX UI extension's dialog set:
  • With WiX .NET Tools, this is the Id of the <ui:WixUI> element in the default WiX template.
  • With WiX Toolset v3, this is the Id of the <UIRef> element in the default WiX template.

The default is WixUI_InstallDir in case no CPack components have been defined and WixUI_FeatureTree otherwise.


The bitmap will appear at the top of all installer pages other than the welcome and completion dialogs.

If set, this image will replace the default banner image.

This image must be 493 by 58 pixels.


Background bitmap used on the welcome and completion dialogs.

If this variable is set, the installer will replace the default dialog image.

This image must be 493 by 312 pixels.


Start menu folder name for launcher.

If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME

Added in version 3.16: If this variable is set to ., then application shortcuts will be created directly in the start menu and the uninstaller shortcut will be omitted.


Language(s) of the installer

Languages are compiled into the Wix UI extension library. To use them, simply provide the name of the culture. If you specify more than one culture identifier in a comma or semicolon delimited list, the first one that is found will be used. You can find a list of supported languages at: https://wixtoolset.org/docs/v3/wixui/wixui_localization/


Template file for WiX generation

If this variable is set, the specified template will be used to generate the WiX wxs file. This should be used if further customization of the output is required. The template contents will override the effect of most CPACK_WIX_ variables.

If this variable is not set, the default MSI template included with CMake will be used.


Optional list of XML files with fragments to be inserted into generated WiX sources.

Added in version 3.5: Support listing multiple patch files.

This optional variable can be used to specify an XML file that the WIX generator will use to inject fragments into its generated source files.

Patch files understood by the CPack WIX generator roughly follow this RELAX NG compact schema:

start = CPackWiXPatch
CPackWiXPatch = element CPackWiXPatch { CPackWiXFragment* }
CPackWiXFragment = element CPackWiXFragment
{


    attribute Id { string },


    fragmentContent*
}
fragmentContent = element * - CPackWiXFragment
{


    (attribute * { text } | text | fragmentContent)*
}


Currently fragments can be injected into most Component, File, Directory and Feature elements.

Added in version 3.3: The following additional special Ids can be used:

  • #PRODUCT for the <Product> element.
  • #PRODUCTFEATURE for the root <Feature> element.

Added in version 3.7: Support patching arbitrary <Feature> elements.

Added in version 3.9: Allow setting additional attributes.

The following example illustrates how this works.

Given that the WIX generator creates the following XML element:

<Component Id="CM_CP_applications.bin.my_libapp.exe" Guid="*"/>


The following XML patch file may be used to inject an Environment element into it:

<CPackWiXPatch>


  <CPackWiXFragment Id="CM_CP_applications.bin.my_libapp.exe">


    <Environment Id="MyEnvironment" Action="set"


      Name="MyVariableName" Value="MyVariableValue"/>


  </CPackWiXFragment>
</CPackWiXPatch>



Extra WiX source files

This variable provides an optional list of extra WiX source files (.wxs) that should be compiled and linked. The paths must be absolute.


Extra WiX object files or libraries to use with WiX Toolset v3.

This variable provides an optional list of extra WiX object (.wixobj) and/or WiX library (.wixlib) files. The paths must be absolute.


Specify a list of additional extensions for WiX tools. See WiX Toolsets for extension naming patterns.

Specify a list of additional extensions for a specific WiX tool. See WiX Toolsets for possible <TOOL> names.

Specify a list of additional command-line flags for a specific WiX tool. See WiX Toolsets for possible <TOOL> names.

Use it at your own risk. Future versions of CPack may generate flags which may be in conflict with your own flags.


If this variable is set the generated installer will create an entry in the windows registry key HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<PackageName> The value for <PackageName> is provided by this variable.

Assuming you also install a CMake configuration file this will allow other CMake projects to find your package with the find_package() command.


Added in version 3.1.

This variable can be used to provide a value for the Windows Installer property <PROPERTY>

The following list contains some example properties that can be used to customize information under "Programs and Features" (also known as "Add or Remove Programs")

  • ARPCOMMENTS - Comments
  • ARPHELPLINK - Help and support information URL
  • ARPURLINFOABOUT - General information URL
  • ARPURLUPDATEINFO - Update information URL
  • ARPHELPTELEPHONE - Help and support telephone number
  • ARPSIZE - Size (in kilobytes) of the application


Added in version 3.7.

Sets the name of the root install feature in the WIX installer. Same as CPACK_COMPONENT_<compName>_DISPLAY_NAME for components.


Added in version 3.7.

Sets the description of the root install feature in the WIX installer. Same as CPACK_COMPONENT_<compName>_DESCRIPTION for components.


Added in version 3.7.

If this variable is set to true, the default install location of the generated package will be CPACK_PACKAGE_INSTALL_DIRECTORY directly. The install location will not be located relatively below ProgramFiles or ProgramFiles64.

NOTE:

Installers created with this feature do not take differences between the system on which the installer is created and the system on which the installer might be used into account.

It is therefore possible that the installer e.g. might try to install onto a drive that is unavailable or unintended or a path that does not follow the localization or convention of the system on which the installation is performed.






Added in version 3.9.

This variable allows specification of a custom root folder ID. The generator specific <64> token can be used for folder IDs that come in 32-bit and 64-bit variants. In 32-bit builds the token will expand empty while in 64-bit builds it will expand to 64.

When unset generated installers will default installing to ProgramFiles<64>Folder.


This variable can optionally be set to the root directory of a custom WiX Toolset installation.

When unspecified CPack will try to locate a WiX Toolset installation via the WIX environment variable instead.


Added in version 3.19.

This variable provides a list of custom namespace declarations that are necessary for using WiX extensions. Each declaration should be in the form name=url, where name is the plain namespace without the usual xmlns: prefix and url is an unquoted namespace url. A list of commonly known WiX schemata can be found here: https://wixtoolset.org/docs/v3/xsd/


Added in version 3.23.

If this variable is set to true, the default inclusion of the WiX UI extension is skipped, i.e., the -ext WixUIExtension or -ext WixToolset.UI.wixext flag is not passed to WiX tools.


Added in version 3.24.

This variable can be optionally set to specify the target architecture of the installer. May for example be set to x64 or arm64.

When unspecified, CPack will default to x64 or x86.


Added in version 3.29.

This variable can be optionally set to specify the InstallScope of the installer:

Create an installer that installs for all users and requires administrative privileges. Start menu entries created by the installer are visible to all users.

This is the default if CPACK_WIX_VERSION is set to any value other than 3.

Not yet supported. This is reserved for future use.
Create an installer without any InstallScope attribute.

If CPACK_WIX_VERSION is not set, or is set to 3, this value is the default to preserve compatibility with 3.28 and lower. Otherwise, this value is not supported.

Deprecated since version 3.29: This value is only for compatibility with the inconsistent behavior used by CPack 3.28 and older. The resulting installer requires administrative privileges and installs into the system-wide ProgramFiles directory, but the start menu entry and uninstaller registration are created only for the current user.

WARNING:

An installation performed by an installer created without any InstallScope cannot be cleanly updated or replaced by an installer with an InstallScope. In order to transition a project's installers from NONE to perMachine, the latter installer should be distributed with instructions to first manually uninstall any older version.
