FYI, we do this in CMake's own build:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/CMakeVersionSource.cmake;hb=v2.8.8

though the implementation pre-dates FindGit.cmake so it does not use
find_package(Git) as a new implementation should.

It does require a Git command line tool to be found during CMake
configuration of the project though.  To do that on Windows one should
use find_package(Git) and require CMake >= 2.8.2 to reliably find
msysGit.
