[CMake] Combined 32-bit / 64-bit project files for Visual Studio

[Paul Richards]

Visual Studio supports both 32-bit and 64-bit builds using the one set
of project files.  Can CMake produce VS project files that use this
feature?  Currently I only see options to produce only one or the
other (ie "32-bit only" or "64-bit only" project files).
