Well, is where we install the configs. In my case: ``/etc/kamailio``
here is where is it set https://github.com/kamailio/kamailio/blob/b6f25031590e472f0f63b3e2a4fa61dad9...
And here is where is defined previously https://github.com/kamailio/kamailio/blob/b6f25031590e472f0f63b3e2a4fa61dad9...
Notice that I don't want to change ``CMAKE_INSTALL_SYSCONFDIR`` that is fine pointing to ``etc`` I want to be able to define where the configs should be installed and ``/usr/etc/kamailio`` is not it.
So please allow me to define ``CFG_DIR`` somehow and use that value if is defined
