[CMake] MSVC_VERSION for VC11?

[Robert Dailey]

I actually need to check the compiler version for ABI compatibility
reasons. I download my third party libraries via CMake script and I check
the current compiler version so I know which DLLs to download :P

Unfortunately C++ name mangling is not standardized so this is necessary.

Also it is quite possible to have the pimpl pattern in my code base,
designed in such a way that different CPP files are included in my targets
depending on compiler version. It's a way to abstract away
platform-specific and compiler-specific implementation details (Perhaps I
use MSVC-specific extensions in my pimpl class, or maybe I do some inline
assembler to overcome a specific optimization failure or inefficiency in
older versions of MSVC).

Need more examples? :P
