Support CMake 4.0

[LecrisUT]

Please update the cmake_minimum_required to something like cmake_minimum_required(VERSION 3.5...4.0).

ipmctl/CMakeLists.txt

Line 4 in d2caed1

cmake_minimum_required(VERSION 2.8.12)

I did not do a thorough check if this needs to be patched in other places also, but feel free to ping if more discussion is needed.
