 **NOTE**: As of now, Ubuntu's `apt` only has until CMake version 3.16.3 if you're using Ubuntu 20.04 LTS (less in older Ubuntu versions), and version 3.18.4 in Debian 11 (less in older Debian versions). This is lower than the required 3.20, which in turn makes it incompatible with the repo. For this case, we can use the `snap` package manager or the _Kitware APT feed_ to get a new enough version of CMake.
