dnl
dnl Define a macro to enable backends.
dnl - Macro: CAIRO_BACKEND_ENABLE (NAMESPACE, NAME, ARG, FEATURE_NAME, DEFAULT, COMMANDS)
dnl
dnl where:
dnl
dnl NAMESPACE is the sub-namespace in function names, eg. "ft" for cairo_ft_...
dnl NAME is the human-readable name of the backend, eg. "FreeType font"
dnl ARG is what enables the backend, eg. "freetype" for --enable-freetype
dnl FEATURE_NAME is what's used in cairo-features.h, eg. FT_FONT for CAIRO_HAS_FT_FONT
dnl DEFAULT is the default state of the backend:
dnl "no" for experimental backends, eg. your favorite new backend
dnl "yes" for mandatory backends, eg. png
dnl "auto" for other supported backends, eg. xlib
dnl COMMANDS are run to check whether the backend can be enabled. Their
dnl result may be cached, so user should not count on them being run.
dnl They should set use_$(NAMESPACE) to something other than yes if the
dnl backend cannot be built, eg. "no (requires SomeThing)". It then
dnl should also set $(NAMESPACE)_REQUIRES/CFLAGS/LIBS/...
dnl appropriately. Look at the macro definition for more details,
dnl or ask if in doubt.
