@ -288,6 +288,9 @@ FLTK_OPTION_SVG - default ON
FLTK has a built-in SVG library and can create (write) SVG image files.
Turning this option off disables SVG (read and write) support.
FLTK_USE_DBUS - default ON (Wayland only).
Meaningful only under Wayland. Allows FLTK to detect the current cursor theme.
FLTK_USE_LIBDECOR_GTK - default ON (Wayland only).
Meaningful only under Wayland and if FLTK_USE_SYSTEM_LIBDECOR is 'OFF'.
Allows to use libdecor's GTK plugin to draw window titlebars. Otherwise
