To ensure the broadest compatibility when building the benchmark library, but still allow forward progress, we require any build tooling to be available for:
Currently, this means using build tool versions that are available for Ubuntu 18.04 (Bionic Beaver), Ubuntu 20.04 (Focal Fossa), and Debian 11 (bullseye).
Note, CI also runs ubuntu-16.04 and ubuntu-14.04 to ensure best effort support for older versions.
The current supported version is cmake 3.5.1 as of 2018-06-06.
Note, this version is also available for Ubuntu 14.04, an older Ubuntu LTS release, as cmake3.
