$NetBSD: patch-meson.build,v 1.17 2022/07/24 21:24:56 wiz Exp $

- On Darwin, optionally use Cocoa (needed for X11 users).

- Don't insist that Python binary is called "python3".
  (Requires meson >= 0.50.0)

- Don't install bash completion scripts.

- Tolerate getxattr not existing (smartOS)
  https://gitlab.gnome.org/GNOME/glib/merge_requests/888

- Define a newer POSIX, as we build this package with -std=gnu99
