We're severely behind in cleaning out deprecated Gtk code so anything from around 3.10 should work OK. Glade is another matter, Bob Fewell keeps regenerating the Glade files with new versions. I avoid the problem by using emacs on glade files, but otherwise you need to keep up to date. Maybe Bob can jump in with some more advice.

The part of GnuCash that you're interested in is single-threaded. Guile and WebKit fire off some threads for their own nefarious purposes but you can ignore them.

CMAKE_BUILD_TYPE=Debug doesn't turn off optimization, you need to add -O0 or -O1 to CMAKE_CPP_FLAGS if you need to have all of your locals and args populated and your code to step linearly.

We have an IRC channel, see https://wiki.gnucash.org/wiki/IRC, with some of the core team usually present.
