[cfe-dev] LibTooling CMake Error

Maybe we could bake those header files directly into libFrontend?

It's a bit extreme, but I think that it is probably the right thing to
do here, since to be honest, it is simply unacceptable for a library
to force its clients to run their tool from directories with
particular directory layouts, or to install in a particular place.
Imagine if, say, zlib would not function correctly without a
configuration file "../share/zlib/zlib.conf", or something like
that---there would be outrage.
