[CMake] CMake Variables for MSVC

[Michael Jackson]

I noticed a few things while writing some code to parse the CMake  
documentation:

There are the following CMake Defined variables:

MSVC
MSVC80
MSVC_IDE
MSVC_VERSION

I see that MSVC70, MSVC71 and MSVC90 are defined in the Windows- 
cl.cmake file? Is it a bug that MSVC80 is being formally defined in  
the documentation? Should the other MS compilers be defined also or  
should the MSVC80 docs be removed?

Is CMake moving towards another mechanism to detect which MSVC  
Compiler is being used? (MSVC_VERSION)?


Thanks
