# 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:

CPACK_DMG_VOLUME_NAME

  The volume name of the generated disk image. Defaults to CPACK_PACKAGE_FILE_NAME.

CPACK_DMG_FORMAT

  The disk image format. 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. Defaults to `UDZO`.

CPACK_DMG_DS_STORE

  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.

CPACK_DMG_DS_STORE_SETUP_SCRIPT

  New 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.

CPACK_DMG_BACKGROUND_IMAGE

  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.

CPACK_DMG_DISABLE_APPLICATIONS_SYMLINK

  New 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.

CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE

  New in version 3.23.

  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.

CPACK_DMG_SLA_DIR

  New 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.

  New in version 3.17: RTF support.

CPACK_DMG_SLA_LANGUAGES

  New 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.

CPACK_DMG_<component>_FILE_NAME

  New in version 3.17.

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

  - Default: `CPACK_PACKAGE_FILE_NAME-<component>`

CPACK_DMG_FILESYSTEM

  New in version 3.21.

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

CPACK_COMMAND_HDIUTIL

  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).

CPACK_COMMAND_SETFILE

  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).

CPACK_COMMAND_REZ

  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).
