I'm not sure how well find_program will work if path to <build directory>/bin will be not added to PATH, so probably will be good idea to allow LLVM_CONFIG to be set in Cmake command line and use find_program only if LLVM_CONFIG is not set.

But it's necessary to pass path from CMake command line argument to find_program after PATHS. Another problem if default OS location (if Clang installed and of old version) will be returned instead of build one.
