Bug 267784: devel/evdev-proto: provide pkg-config support
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267784



--- Description ---
Projects outside of ports/ would like to support FreeBSD evdev (mainly via
Wayland) without hardcoding -I/usr/local/include in build glue or CI config.
pkg-config would cover Meson + autotools and maybe CMake. Currently, this is
worked around via USES=localbase in ports/.

Example:

$ cat foo.c
#include <linux/input-event-codes.h>
#include <stdio.h>

int main()
{
  printf("<F1> evdev code: %d\n", KEY_F1);
  return 0;
}

$ cat meson.build
project('foo', 'c')

evdev_proto = dependency('evdev-proto', required: false) # DragonFly, FreeBSD

executable('foo', files('foo.c'), dependencies: evdev_proto)
