Diego Biurrun 7208e5b5d6 configure: Restructure the way check_pkg_config() operates Have check_pkg_config() enable variables and set cflags and extralibs instead of relegating that task to require_pkg_config. This simplifies require_pkg_config(), is consistent with what other helper functions like check_lib() do and allows getting rid of some manual variable setting in places where check_pkg_config() is used.		2017-02-20 20:16:05 +01:00
