[CMake] Automatically add a revision number to the CPack installer name

[Michael Jackson]

I do something like this in my CPack file:

set(DREAM3D_VERSION_SHORT "${DREAM3DLib_VER_MAJOR}.${DREAM3DLib_VER_MINOR}")

set(CPACK_PACKAGE_FILE_NAME "DREAM3D-${DREAM3D_VERSION_SHORT}-${CMAKE_SYSTEM_NAME}")


Where the DREAM3D_Lib_VER_* variables are generated with a call to my SCM (git in my case)

I understand that to get the revision number at build time one must run a command and I have used that technique to generate a source code header, but I cannot figure out how to apply it to the package file name. The simplest method would appear to be to add a post-build command that renames the file to the package target, but it appears that this cannot be currently done [1].
