This makes me believe your clang build is not using the llvm you just
built? Do you have installed version of LLVM on your distro?

I used to build Clang out of source on Windows and you had to provide path
to LLVM but I can't see that in CMake gui anymore (on Linux). The only
thing I can suggest is to move clang inside llvm/tools and build in-tree.
That will work 100%
