Yep, found that too.

    I'll suggest an examples/cairo-draw-x.cxx on fltk.coredev.

OK, +1

    To do so would mean some kind of conditional in the examples/Makefile* and examples/CMakeLists.txt
    to only build the example if cairo is enabled.

In the latest 1.4 commits we have <FL/fl_config.h> which is automatically included and defines FLTK_HAVE_CAIRO if cairo is available. test/cairo_test.cxx shows how to use it and how to display an alternate message if cairo is not available. I suggest to do it like this.

I'm going to remove libfltk_cairo soon, so linking with that should not be a problem (fltk-config could help anyway).

Linking with libcairo (or not) would be another issue I'll attack at least with CMake. Makefiles could either use ../makeinclude or a combination of fltk-config options. But that's only thoughts so far...

    I have something that works, but I'll probably open a separate thread on fltk.coredev
    about that.

OK.

Greetings from 2022 (Jan 1, 0:25 am) back to 2021 ;-)
Happy new year to all !

    Oh wow, so is 2022 is any better, or should I stick with 2021 and hold off on "upgrading"? :D

I hope it'll be better (less COVID issues, hopefully), but I can't downgrade anyway. Looking forward to its new features... ;-)
