Mir fails to build with Wayland master, and cmake v3.22.0, linking with wl_proxy_marshal_flags

[n3rdopolis]

It oddly builds with v3.20.0
wl_proxy_marshal_flags in Wayland Master caused problems building some other things, but it's odd that this seems to happen with a new version of cmake.

Below is the error output I get

I tested with cmake 3.21.0 and that worked, so it could be a cmake regression in 3.22

CNR: cmake 3.22.1 has been and is working fine on 22.04. (Not tried 3.22.0, but unlikely to be a Mir problem.)

Still happening with v3.22.0 since now KDE needs CMake 3.22
Be sure to use the newest libwayland I think the issue must be combined with the CMake version and a change in libwayland, other things around this time had problems with wl_proxy_marshal_flags that were later fixed
