[CMake] How to have Visual Studio 15 2017 actually use a 64 bit toolchain.

[Michael Jackson]

So I tried using "-DCMAKE_GENERATOR_TOOLSET=x64" while configuring a clean build directory but it still picked up the x86 compiler. I ended up going into the "Settings" of Windows 10 and added the environment variable PreferredToolArchitecture=x64 to my account. Logged out, Logged back in and then did another configuration run and now during the cmake configuration run the proper 64 bit compiler is picked up and used. Still probably missing something obvious in the CMake file that I can add....

    Isn't host=x64 for that purpose?
