[CMake] CMake 2.8.1 RC 4 is ready to try

[Bill Hoffman]

CMake 2.8.1 RC 5 is ready to try:

http://www.cmake.org/files/v2.8/?C=M;O=D

Please try your projects with it.   If you find any issues, let me know.
I think this is about it.  I only had two small fixes over RC 4, so this 
should be it. (The source trees should no longer have full git 
repositories in them.)

Thanks.
