[CMake] Is there any way to use clang-cl with MSBuild on Windows?

[Nicholas Braden]

Have you tried setting the toolset? The -T parameter can set the
toolset. This sets the platform toolset property that you would
normally set in Visual Studio. if Visual Studio lets you select the
llvm platform toolset, so will CMake.
