cmake: Look in popular places for X11 headers, export this info properly. 

Fixes CMake not being able to find X11 on FreeBSD (which generally has the
headers in /usr/local/include/X11).

List of other popular places borrowed from CMake's FindX11 module.

This worked on the configure script because of magic in the AC_PATH_X macro.

Fixes Bugzilla #4815.
