WARNING: Running the setup command as `meson [options]` instead of `meson setup [options]` is ambiguous and deprecated.

From meson(1):
The setup command is the default operation. If no actual command is
specified, Meson will assume you meant to do a setup. That means that
you can set up a build directory without the setup command like this:
meson [ options ] [ build directory ] [ source directory ]
