I suspect that it's not trivial. You can try to ask the GTK developers on https://discourse.gnome.org/c/platform/core. Gtkmm is just a C++ wrapper around most of GTK.I should ask you to improve the support.This is free and open software. You don't pay. No one is responsible for any support. Users of gtkmm can help each other. One user can answer another user's questions.
I've built my way most of the examples of the gtkmm programming tutorial, and all of them worked for me. But the drug and drop example isn't in the list so far. On the other hand, I admit that I didn't give a try to gtk4 because the existing .deb packages are still in the unstable repository of debian (sid). Hence, I'll need to upgrade my system or build my own images of the unstable/testing branch. Once I have done this, I'll try to get the DnD example working. I hope that it'll be within a few days.
Cheers,
Aitor.
