cmake28 package - CMake 2.8.x for EL6

[Jonathan Underwood]

Hi,

Presently RHEL6 is shipping with CMake 2.6.x, and there seems to be no
interest from the maintainer in updating the RHEL packages to CMake
2.8.x. So, I made a parallel installable cmake28 package (with all
binaries renamed to cmake28 etc). Review request here:

Comments, reviews etc welcome.

Cheers,
Jonathan.
