# CPackPackageMaker

PackageMaker CPack generator (Mac OS X).

## Variables specific to CPack PackageMaker generator

The following variable is specific to installers built on Mac OS X using PackageMaker:

`CPACK_OSX_PACKAGE_VERSION`

  The version of Mac OS X that the resulting PackageMaker archive should be compatible with. Different versions of Mac OS X support different features. For example, CPack can only build component-based installers for Mac OS X 10.4 or newer, and can only build installers that download component son-the-fly for Mac OS X 10.5 or newer. If left blank, this value will be set to the minimum version of Mac OS X that supports the requested features. Set this variable to some value (e.g., 10.4) only if you want to guarantee that your installer will work on that version of Mac OS X, and don’t mind missing extra features available in the installer shipping with later versions of Mac OS X.
