+Subject: [PATCH] cmake: Set minimum required version to 3.5 for CMake 4+
+ compatibility
+
+Fix:
+
+| 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.
+|
+|
+| -- Configuring incomplete, errors occurred!
+
+Upstream-Status: Backport [https://github.com/Matroska-Org/libmatroska/commit/dc80e194e93e6f0e25c8ad3e015d83aca2a99e10]
