Qt Wayland Client

The Qt Wayland Client library provides the necessary functions for an application to act as a Wayland client and connect to a Wayland compositor. For most use cases, the library is used automatically through the Wayland QPA plugin, and there is no need for the application itself to use any functions from the library.

However, when paired with Qt Wayland Compositor, the cmake function qt_generate_wayland_protocol_client_sources() can be used to create custom protocol extensions.
