[cmake-developers] [PATCH] Don't use /ZmXXXX for MSVC11+

Thu, 15 Nov 2012 05:37:57 -0800 

    /Zm1000 considered harmful in VS2012 (this is probably true of >=VS2005 - 
but I've erred on the side of leaving things alone for configurations I haven't 
tested.)
    Only use /Zm on MSVC versions older than 11.
    This was making each compiler instance reserve around 750MB immediately, 
which in a parallel build would make some or all of the spawned compilers crash 
depending on system memory pressure.
    See: http://msdn.microsoft.com/en-us/library/bdscwf1c.aspx

Cheers,
--Adam
