This is a problem with the FindNL.cmake file which puts the wrong
NL_INCLUDE_DIR in the cache if you install libnl3-devel after running
cmake with libnl-devel installed. If you clean CMakeCache.txt and start
over after installing, it seems to work (I tested it on CentOS 6).

Will look into this.

Kind regards,
Peter
