^ I think you need to add some cmake flag/patch so that i only picks up llvm60, as it checks against multiple versions, it could be, possibly, that it would use llvm50 if that is also installed.
^ this is probably an existing error in the plist -- and os supposed to be
unless it is indeed
Judging from FindLLVM.cmake/FindClang.cmake, it starts searching from a newest version. And since llvm60 is now guaranteed to be pulled in as dependency, I think there is no need in explicit setting of LLVM version in Makefile.
Yep, it is debug when building WITH_DEBUG=1.
