To guarantee we have a matching and capable `clang` we generally like `clang` to be in the enabled projects and openmp in the enabled runtimes (-DLLVM_ENABLE_RUNTIMES="openmp"). Since you build with clang we could verify if the version is recent enough and use it. We also might not need any of this because you don't build the target stuff (explicitly) so we could disable that part and go with whatever compiler was chosen.
