[CMake] Compiler identification?

[Bradley Lowekamp]

Hello,

I need to detect if MS Visual Studio 9 (2008) has SP1 applied. During configuration I see lines like:

-- The C compiler identification is MSVC 15.0.30729.1
or
-- The C compiler identification is MSVC 15.0.21022.8


I am wondering if this information is available as a cmake variable. Or is there some other standard module I should be using? Know I can do a try_run to get it... But that seems excessive.

Thanks,
Brad
