+Subject: [PATCH] cmake: Set minimum required version to 3.5 for CMake 4+
+ compatibility
+
+Fix:
+
+| CMake Error at CMakeLists.txt:27 (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.
+|
+|
+| -- Configuring incomplete, errors occurred!
