Hi Mijenko,
You are not meant to modify the source directory, pass the variable
names. Just pass them as arguments:

cmake -DCMAKE_BUILD_TYPE=Debug ....

Also you need to make sure you are running the software you just
built. I'd recommend uninstalling the one the distro provides and
installing to a separate prefix. Also note "make install" needs to be
called so the binaries are placed somewhere useful.
