MinGW is not supported. Clang provides a Visual C++'s cl.exe replacement. You need to have the official windows <http://llvm.org/releases/download.html#3.8.0> Clang and Visual C++ Express or Community installed. Then it's just a matter of: 1. Opening a Visual C++ 2013 64 bit command prompt window 2. Putting clang's cl.exe in the path and setting clang's INCLUDE path first set PATH=c:\Program Files\LLVM\msbuild-bin\;%PATH% set INCLUDE=c:\Program Files\LLVM\lib\clang\3.8.0\include\;%INCLUDE% 3. cmake -G "Ninja" 4. Ninja CMake / Ninja will think that they compile with Visual C++, but instead will use clang. Note that you have to match Visual C++ and Clang's build, 32 or 64 bit. You can't mix them, or you'll have weird errors <https://cmake.org/pipermail/cmake/2016-March/062978.html>. Cheers, Cristian. P.S. This is actually a re-post, this time adding the mailing list.
