This commit introduces build script configuration for building a shared library 'libinput.so' containing the evdev input device functionality from weston. evdev.c, evdev.h and evdev-touchpad.c are ported to not use the data structures and API in weston and libwayland-server in order to minimize dependencies. The API of filter.c and filter.h are renamed to not include the 'weston_' prefix. Signed-off-by: Jonas Ådahl <jadahl@gmail.com>
