There is an outstanding issue with FLTK that seems to prevent
on Windows to run the widgets from a FLTK host (ie. Csound5GUI)
at least on my windows build.
It also seems to prevent the virtual midi keyboard to work with
widgets. The FLTK widget code is so horrid that I feel relatively
unmotivated to do something about it.

However, widgets work fine from the command-line, on their
own.
