cmake: bump minimum version to address a deprecation warning

Browse Source 
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.
