Then use CMake to configure & build cling:

mkdir build
cd build
cmake --build .
cmake --build . --target install

cling patches?

Cling needs a couple of patches on top of clang (but can work with an original build of llvm). These are the commits that above build instructions correspond to - which is mostly interesting to package maintainers:
