Summary:                    CMakeDetermineVSServicePack.cmake uses try_compile
to get the compiler version.  cl.exe /? is much faster
Description: 
Using try_compile(), there is a lot more work going on than is necessary
just to get the version from the compiler. It is present at the top of the
help output in the same format.  I've modified the script to use that
command instead and it is quite a bit faster at picking out the version of
the compiler.

Patch attached.
