None of these solutions relieves you from building your binary at the
same place at Clang is installed, or duplicate the Clang headers along
your tool installation so that they are in PATH_TO_BIN/../lib/...

From my (very shallow) experience, unless you get very deep with the
initialization it end up by looking the headers from the place the
binary is installed.
