Apologies if this isn't the right place for this!
But I'm encountering weird behavior with cmake project generation with MSVC when I'm using Clang codegen. I suspect I may be rolling into the "currently unsupported" territory here, but I wanted to give it a shot to see cross compiling could be possible.
Generating a project with "v140_clang_c2" toolset it seems to not find some bundled libraries:
$ cmake -G"Visual Studio 14 2015" -T"v140_clang_c2" "C:\Users\tehph\OneDrive\Projects\github\GameEngine\extinclude\SFML-repo"

I found setting CMAKE_LIBRARY_PATH manually seems to workaround this:

But I seem to encounter a compilation failure after shortly trying to build said generated project:

Errors seem to indicate that its because the toolset isn't happy with a <windows.h> include:
https://connect.microsoft.com/VisualStudio/feedback/details/3005617/clang-platform-toolset-unable-to-compile-any-project-that-includes-windows-hSo seems like a long shot, but has anyone else got this working?
