CMake: Add doxugen build via custom target, fix configure_files, and update doxygen file.

- Doxygen documentation cann be built via 'make doc' in build dir if you have doxygen
  - configure_files now configure output to build dir
  - update doxygen file to latest revision accepted by doxy (doxygen -u)
