## Detailed Description

Cairo is currently supported for the following platforms: Windows, macOS, Unix/Linux (X11 + Wayland).

Note
  In FLTK 1.3.x this header file (Fl_Cairo.H) included the platform specific Cairo headers. This is no longer true since 1.4.0.

This header file is platform agnostic. If you need platform specific Cairo headers you need to #include them in your source file.

To use FLTK's builtin Cairo support you need to #include <FL/Fl.H> before you include any other FLTK header which is officially required anyway. Since FLTK 1.4.0 the preprocessor constants `FLTK_HAVE_CAIRO` and/or `FLTK_HAVE_CAIROEXT` are defined in <FL/Fl.H> by including <FL/fl_config.h>.
