+Subject: [PATCH] Raise CMake minimum to 3.10...3.16 range
+
+CMake >=3.31 warns about compat. for <3.10 being removed in the future.
+
+Make 3.10 was released in 2017 and is available in Ubuntu Bionic, which is
+referenced in the root CMakeLists.txt. The version range upper limit lets
+others at least test at the same policy level as the 3.16 minimum from ECM.
