Allow build outside of clang source tree

Question

Originally reported on Google Code with ID 64

Hi

I would like to package your work into Debian. However, the fact that include-what-you-use
needs the clang source tree greatly complexifies the build process.
It would be nice if you could update your work to build against clang headers and libs.
Here is a list of headers provided by the libclang-dev package in Debian and Ubuntu:

That would be great to get this into debian!  I'll help how I can.  Unfortunately, the
build system for clang is a bit of a black box for me.

I do have a version of iwyu that is built against llvm-3.0.  Assuming your libclang-dev
is for llvm-3.0, you should be able to use that:

I believe that if you unpacked that tarball, it would be a single compile command --
possibly a long one -- to build iwyu against the llvm/clang headers.  But I don't know
if that's exactly what you're looking for.  I can come up with the clang command if
that would help; or else let me know what would.
