+Subject: [PATCH] xdg-shell: Add CMake minimum
+
+The build is broken:
+```
+| CMake Error in CMakeLists.txt:
+|   No cmake_minimum_required command is present.  A line of code such as
+|
+|     cmake_minimum_required(VERSION 4.1)
+|
+|   should be added at the top of the file.  The version specified may be lower
+|   if you wish to support older CMake versions for this project.  For more
+|   information run "cmake --help-policy CMP0000".
+```
