I'm wondering about things like clang, lldb, etc. that are checked out
in llvm's projects directory.  Is there a way to skip building one of
them?  The lldb build is failing due to an ancient libc I can't replace.

Yeah, I can just delete the directory but for various reasons it's more
attractive not to have to do that.  It would be nice to just tell CMake
not to build that directory via a CMake variable or at build config
time.
