Nope, unfortunately in order to use the newer protocol we need to link to
libwayland >= 1.6

Recent versions of Wayland (>= 1.8) should let us target a new protocol
version while linking to an older version mitigating the problem in the
future, but still Ubuntu is probably not the best option for Wayland.
