[cfe-dev] Pointing clang to a C++ library

[David Greene via cfe-dev]

I've got clang built to a point where it can find the gcc toolchain it
was built with and use that gcc toolchain's C++ library.

But I want it to point to a different C++ library.  That library will be
installed relative to where clang will be installed.  Pointing clang to
an absolute path isn't going to work because the package may be
installed in lots of different places.

What's the best way to do this?

Thanks!
