+Subject: [PATCH] cmake: bump minimum version to address a deprecation warning
+
+This fixes the following warning shown while configuring:
+
+  [cmake] CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
+  [cmake] Compatibility with CMake < 3.10 will be removed from a future version of
+  [cmake] CMake.
+
+We don't have a clearly defined supported distro/versions list, so I
+took Ubuntu 22.04 as arguably the oldest one we'd want to support for
+the reference point. It has CMake 3.22, released in July 2022.
