+Subject: [PATCH] Update cmake_minimum_required to 3.5
+
+This supports compilation with cmake-4.0.0.
+
+Fixes:
+CMake Error at CMakeLists.txt:5 (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.
