I changed the top line in Sander's CMakeLists.txt to: 

	cmake_minimum_required(VERSION 3.28)

And it appeared to compile w/o a hitch.

At least on Linux there doesn't seem to be a compelling need for cmake4.

I am planning to come up with cmake config which requires some version
of cmake3 or up; it seems the most common out there at this point.

I should check what version is on current raspbian operating system
as well, as I'm planning to extend support for aarch64.
