Hello all.
I'd like to propose we update the required CMake version to be 3.18 (the current minimum version for macOS). This is two releases behind the current RC (3.20). If anyone is still using an old CMake, we already have the infrastructure to bootstrap a newer version as part of the build process. Are there any objections to doing this from the community?
