Right - I was assuming a layout where the subprojects are already in the
places they need to be checked out to. With llvm-project's layout my
question is silly.
llvm-project's layout is kind of annoying, since with that I have to
check out all of the repos yet I still need to add symlinks or something
to actually use any of them. It also means that anyone who is only using
llvm has to change their paths from /path/to/llvm to /path/to/llvm/llvm,
which is a little bit ugly.
