That is odd. Inside your build/CMakeFiles should be a file called feature_tests.cxx, and that file is how we determine what features the clang compiler supports.
I would use that to determine why feature detection is failing, since currently it believes that none of the features listed in it are valid. Now if the file is empty, that means we are looking at a CMake logic bug somewhere before this.
