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

[Glenn Ramsey]

Hi Mike,

When, during the build process is the call to the SCM made? If it is at build 
time, rather than cmake time, then how do you do it?

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].
