I chose the binaries behaving like "gcc": After installation I added the "bin" directory to my PATH (actual command "set path=e:\work\install\LLVM\bin;%PATH%"). In the new bin-directory there are binaries called "clang.exe" and "clang++.exe" + a bunch of other binaries eg. "clang-cl.exe". I did NOT put the directory "e:\work\install\LLVM\msbuild-bin" in my PATH (containing a binary "cl.exe"). I realize that Cristian Adams recommended using the "cl.exe" wrapper in his response, but I wanted at least to try using the "gcc-like" binaries first, hoping that they should work with CMake. I will probably try his advice later, but as I understand it, both ways should be possible to get working with CMake. > CMake should start out by printing the compiler id for the C and > CXX compilers.

There were three file created: build/CMakeFiles/3.5.1/CMakeRCCompiler.cmake build/CMakeFiles/CMakeError.log build/CMakeFiles/CMakeOutput.log On my Windows machine I have Visual Studio 2008, 2012, 2013 and 2015.
