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

[Michael Jackson]

Nope. That just tells what _version_ of the compiler suite to use, but not
the architecture.

-- The C compiler identification is MSVC 19.0.24234.1
-- The CXX compiler identification is MSVC 19.0.24234.1
-- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual
Studio 14.0/VC/bin/x86_amd64/cl.exe
-- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual
Studio 14.0/VC/bin/x86_amd64/cl.exe -- works

C:\Users\mjackson\DREAM3D-Dev\DREAM3D-Builds\Test>set
PreferredToolArchitecture=x64
C:\Users\mjackson\DREAM3D-Dev\DREAM3D-Builds\Test>cmake -G "Visual Studio
15 2017 Win64" -T "v140" -DDREAM3D_SDK=C:/DREAM3D_SDK ../../DREAM3D
