Should we also mention /p:CLToolExe for just swapping out the compiler without using a full toolset?
Also, should we include some notes on cmake usage? I.e. -G "Visual Studio 14 2015" -T "LLVM-vs2014" for the MSVS generator, and -DCMAKE_C_COMPILER=/path/to/llvm/bin/clang-cl.exe -DCMAKE_CXX_COMPILER=/path/to/llvm/bin/clang-cl.exe for the ninja generator? (Don't know if -T works with ninja and/or setting CMAKE_C(XX)_COMPILER works for msvc.) I haven't tested either of these recently, but they all worked at some point and all were useful at some point.
