CMake: fix the $ORIGIN problem

ld does not seem to follow the $ORIGIN in recursive dependencies properly. The
workaround is to specify the recursive dependencies (in this case openssl,
libidn) explicitly, then the rpath is properly constructed and things work at
link time.

Also add full include paths to the dependencies.
