[CMake] Manual version vs CMake version

[Mateusz Loskot]

Hi,

Perhaps it will be helpful information for someone.
On popular Linux distributions CMake 2.6 may not be necessarily the same
CMake 2.6 as documented [1] on the website.

CMake from Ubuntu 9.10  reports "cmake version 2.6-patch 4"
CMake from Debian 5.0.3 reports "cmake version 2.6-patch 0"

It's a micro-difference but may be significant, because on Debian,
for instance, VERSION_LESS or VERSION_GREATER are not available.

I understand it's probably a Debian problem, but users may be confused
while trying to refer to CMake 2.6 documentation.
