Jon TURNEY e67ca94047 meson: An empty array is not a dependency object
Using the meson idiom of initializing a variaible to an empty array to
represent a null value does not work well for a variable expected to hold a
dependency object, as trying to apply found() to it will fail (currently).

I think this can be demonstrated by configuing with Dglamor=no, then gbm_dep
is set to [] in meson.build, and then tested with found() in
include/meson.build.

Use dependency('') to create an empty dependency.

Future work: In the autotools build GBM is required if build_xorg &
build_glamor.  I suspect that it was also required for build_xwayland &
build_glamor, but that was never checked.  That test seems to have gone
missing in meson.build, the required:false when checking for gbm should
possibly be dropped?

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
