# 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, 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.
