While I tend to believe that users of ages old stale^Wstable distributions
shouldn't expect bleeding edge development versions of programs to work on
their systems I'd still like to help with at least the glib/gtk part:

Read [0] and [1], then add the defines to CMakeLists.txt to have them set for
all files. Also make sure that the compiler warns about deprecated functions.
That will bring you half way there. Once the code base compiles without
compiler warnings you can enable -Werror for development builds (i.e., when
there is a .git folder) and you will be sure to stay compatible with those
libraries.

The rest can be done with CI, or just crowd source it and wait for people
complaining when builds fail. :-)
