+In addition, we need to generate suitable xdg shell c code:
+
+```bash
+mkdir $WORK_DIR
+cd $WORK_DIR
+wayland-scanner private-code < /usr/share/wayland-protocols/stable/xdg-shell/xdg-shell.xml > xdg-shell-protocol.cpp
+wayland-scanner client-header < /usr/share/wayland-protocols/stable/xdg-shell/xdg-shell.xml > xdg-shell-client-protocol.h
+export WAYLAND_EXTENSION_DIR=$WORK_DIR
+```
+
+In `xdg-shell-protocol.cpp` - we need access to `xdg_wm_base_interface` so export it also `extern const struct wl_interface xdg_wm_base_interface;` as per similar interface structs.
