and use X11 for their window operations otherwise, but keep using
Cairo and Pango - see README.Wayland.txt.
OPTION_WAYLAND_ONLY - default OFF
In conjunction with OPTION_USE_WAYLAND, restricts FLTK to support the
Wayland backend only.
OPTION_ABI_VERSION - default EMPTY
Use a numeric value corresponding to the FLTK ABI version you want to
build in the form 1xxyy for FLTK 1.x.y (xx and yy with leading zeroes).
