Based on the work by Øyvind Kolås and Pierre Tardy -- many thanks to Pierre for pushing this backend for inclusion as well as testing and reviewing my initial patch. And many more thanks to pippin for writing the backend in the first place! Hacked and chopped by myself into a suitable basis for a backend. Quite a few issues remain open, but would seem to be ready for testing on suitable hardware.

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.
