# CPackDMG

DragNDrop CPack generator (Mac OS X).

## Variables specific to CPack DragNDrop generator

The following variables are specific to the DragNDrop installers built on Mac OS X:

`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 e.g. 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`

  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`

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

`CPACK_DMG_SLA_DIR`

  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` 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.

`CPACK_DMG_SLA_LANGUAGES`

  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_COMMAND_HDIUTIL`

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