Using CLang with MinGW64 on Windows

Hello,

I saw the issue Add support for Clang targeting MSVC ABI but with GNU-like command line.

I'm also trying to be able to use CLang (Based on 6.0.1) properly in Windows under 3 use cases:

1. With MSVC Generator
   I can't achieve this since no matter what I do when -G"Visual Studio 15 2017 Win64" CMake ignore the other variables (-D CMAKE_C_COMPILER=clang-cl -D CMAKE_CXX_COMPILER=clang-cl ..) and use cl for compiling.
2. With Ninja Generator
   If I use x64 Native Tools Command Prompt for VS 2017 I'm able, using the Ninja Generator to use Clang (cmake -G"Ninja" -D CMAKE_C_COMPILER=clang-cl.exe -D CMAKE_CXX_COMPILER=clang-cl.exe -D CMAKE_LINKER=lld-link.exe ..). Yet If I try from different CMD it won't work (Do you know which system variables are needed to configure it correctly?).
3. With MinGW Generator
   I can't make it work with MinGW generator as, by default, clang on windows is targeting MSVC ABI and MSVC flag style. I wonder how can one configure CMake to use clang in MinGW configuration for this generator.

Any ideas on that?

Thank You.
