Hello,
I've noticed that the new "compton" stuff (from tdebase package) does 
not build on RHEL6 :

The libconfig version is 1.3.2 .
There is no "config_set_include_dir" anywhere in /usr/include/* .
Please, either find a way to build on older distro, or make the whole 
feature optional (with a cmake option).

Thanks
François
