The way I understand it is a blanket term to describe both the FLTK
and Qt plotting toolkits and the support libraries needed to make
those work.

Is your question why is the warning phrased the way it is, or why do
you get a warning at all since you intentionally disabled something?

If the latter, that's simply the approach taken for all optional
libraries with Octave, to warn you about what features you might be
missing because of your choices.

Yes. In 4.0.0, there is no way to build the GUI without the Qt
plotting toolkit, which requires OpenGL. If you disable or don't have
OpenGL, the Qt plotting library cannot be built, which means the GUI
is also not built.
