    MSVC Builds: Improve Build Speed and Debugging
    
    Use Multiprocessor compilation which can cut down build times by quite a
    bit and use the /d2Zi+ flag to have better debugging info being logged to
    the .pdb for release builds.
    
    These are only applicable for Visual Studio 2010/2012 and later.
