configure.ac.features [plain text]
dnl
dnl Define macros to enable various features.
dnl - Macro: CAIRO_ENABLE_* (ID, NAME, DEFAULT, COMMANDS)
dnl
dnl where:
dnl
dnl ID is the feature id, eg. "ft" for cairo_ft_...
dnl NAME is the human-readable name of the feature, eg. "FreeType"
dnl DEFAULT is the default state of the feature:
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 feature can be enabled. Their
dnl result may be cached, so user should not count on them being run.
dnl They should set use_$(ID) to something other than yes if the
dnl feature cannot be built, eg. "no (requires SomeThing)". It then
dnl should also set $(ID)_REQUIRES/CFLAGS/LIBS/...
dnl appropriately. Look at the macro definition for more details,
dnl or ask if in doubt.
