libXres cannot find Xutil.h and Xlibint.h

If the files exist as
then you need to remove the /X11 from the end of your CPPFLAGS so that
the compiler can find "X11/Xutil.h" under that path - otherwise you're
telling it to look for .../X11/X11/Xutil.h.   If the files don't exist
at that path, then your installation of libX11 didn't work.

If your pkg-config file doesn't have the right include path, then you need
to fix that - this is a problem with your installation, not the software
provided by X.Org.
