Despite linking my app to Qt6::WaylandClient, the deploy script only deploys a single platform plugin: xcb. The wayland plugin works fine from my build folder but is not found once I deploy to the install folder (because it does not get copied there).

Warning: Could not find the Qt platform plugin "wayland" in ""
