It sounds like the GTK required a modification to

altered? Was it a major change, or only a minor addition?
Bill, I posted a description from Christian
Rauch (libdecor contributor) and links ~2 days ago.
https://gitlab.gnome.org/jadahl/libdecor/-/merge_requests/43
From what I remember the libdecor plugin does not only draw the
title bar, it also needs to react on events (highlighting the
buttons etc.) which seems to have been a not so minor addition. The
primary merge request has been created 11 months ago and they are
still working on it. There have been several commits since ...
My vague impression is the best method for fltk is to
implement this api (by including the source code to libdecor)
on the assumption that it will be able to load more plugins
than the unmodified one. However I don't think fltk should
include any plugins, ...
From what I read I think the intention of the libdecor developers is
that distributions or desktop systems provide plugins that integrate
with different themes of the desktop system. However, as we can see,
there's only one plugin yet (Cairo) and we know of one additional
plugin (GTK) in development.
What Manolo is doing now is to try to get FLTK going with Wayland
and libdecor in its current state. I'm sure this can be modified
later.
In the future, when Wayland is more common and more desktop
environments have implemented their own libdecor plugins I'm sure
that we can use (load) such plugins if they are available on the
user's system, and as Manolo demonstrated, the plugin loading
mechanism works in his test environment.
I agree 100% with Manolo that we need a first step to get us going.
Bundling the (modified) libdecor with FLTK is IMHO absolutely
appropriate until we have a better solution.
@Manolo: Great job, thanks.
