+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!
+
+Upstream-Status: Submitted [https://github.com/nanomsg/nanomsg/pull/1123]
