CPack productbuild Generator

New 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:

CPACK_COMMAND_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).

CPACK_PRODUCTBUILD_IDENTIFIER

New 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.

CPACK_PRODUCTBUILD_IDENTITY_NAME

New in version 3.8.

Adds a digital signature to the resulting package.

CPACK_PRODUCTBUILD_KEYCHAIN_PATH

New in version 3.8.

Specify a specific keychain to search for the signing identity.

CPACK_COMMAND_PKGBUILD

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).

CPACK_PKGBUILD_IDENTITY_NAME

New in version 3.8.

Adds a digital signature to the resulting package.

CPACK_PKGBUILD_KEYCHAIN_PATH

New in version 3.8.

Specify a specific keychain to search for the signing identity.

CPACK_PREFLIGHT_<COMP>_SCRIPT

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.

CPACK_POSTFLIGHT_<COMP>_SCRIPT

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.

CPACK_PRODUCTBUILD_RESOURCES_DIR

New 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.

CPACK_PRODUCTBUILD_DOMAINS

New 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.

CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE

New 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.

CPACK_PRODUCTBUILD_DOMAINS_USER

New 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.

CPACK_PRODUCTBUILD_DOMAINS_ROOT

New 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

New in version 3.17.

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

CPACK_PRODUCTBUILD_BACKGROUND

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

CPACK_PRODUCTBUILD_BACKGROUND_ALIGNMENT

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

CPACK_PRODUCTBUILD_BACKGROUND_SCALING

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

CPACK_PRODUCTBUILD_BACKGROUND_MIME_TYPE

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

CPACK_PRODUCTBUILD_BACKGROUND_UTI

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

CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA

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

CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_ALIGNMENT

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

CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_SCALING

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

CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_MIME_TYPE

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

CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_UTI

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:

CPACK_RESOURCE_FILE_LICENSE_NOPATH

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.

CPACK_RESOURCE_FILE_README_NOPATH

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.

CPACK_RESOURCE_FILE_WELCOME_NOPATH

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.

CPACK_APPLE_PKG_INSTALLER_CONTENT

New in version 3.23.

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

CPACK_PACKAGEMAKER_CHOICES

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.
