Update CMake version compatibility #165

Closed nthallen closed 2 years ago

nthallen commented 2 years ago

Getting complaints about VERSION statements in Monarch:

    Compatibility with CMake < 2.8.12 will be removed from a future version of
      CMake.

      Update the VERSION argument <min> value or use a ...<max> suffix to tell
      CMake that the project does not need compatibility with older versions.

I am currently using: cmake_minimum_required(VERSION 2.8.8)
- Cygwin cmake is currently at 3.20.0
- Raspbian cmake is currently at 3.16.3
Changing this setting can change cmake's behavior, since it affects specific policies that are enabled
- The change therefore requires testing on all platforms
It isn't clear to me whether listing a maximum version will prevent operation when a newer version comes out or just invoke a compatibility mode.
