Description
I'm trying to build opencl-clang 10.0.0-2 on top of Clang 10.0.0 (in the context of getting https://github.com/intel/compute-runtime/releases/tag/20.25.17111 built from source), and I'm running into this problem:

I'm also building Clang 10.0.0 from source myself, so it's possible the -lclang-cpp being linked with isn't what opencl-clang expects it to be...
I have specified the location to the Clang/LLVM installation via -DLLVM_DIR as is explained in the README, so I'm fairly sure that's not the problem here...
Any suggestions on what may be wrong here?
