+Subject: [PATCH] Fix build with cmake 4
+
+Fixes build error with cmake 4.20:
+
+CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
+  Compatibility with CMake < 3.5 has been removed from CMake.
+
+  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
+  to tell CMake that the project requires at least <min> but has been updated
+  to work with policies introduced by <max> or earlier.
+
+  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.
