+Subject: [PATCH] Fix use of private dependency
+
+With 0761173a, Linux SPI Accessibility bridge was added to
+the Wayland QPA plugin, but this had a bad side-effect to
+QtWaylandClient.
+
+Linux Accessibility support is a private module, this means we have
+to link to it with QT_PRIVATE not QT, otherwise CMake and pkg-config
+files for Qt5WaylandClient will depend on it.
