How come the desktops are not providing working libdecor plugins? Or is FLTK not finding and loading them?
The libdecor package is not yet in Linux distros. It's in Debian sid which is the testing version,
and it only has the cairo plugin there. The GTK plugin was a PR to libdecor till a few weeks ago.
For now, FLTK uses its built-in version of libdecor to draw GTK-styled titlebars. And this requires
libgtk-3-dev.
But FLTK is ready for the moment when libdecor plugins will become part of Linux distros
and will load libdecor plugins as soon as they'll appear.
