If you have a built in copy of CMake, it isn't special or customized for your system. You can easily install a new one instead, either on the system level or the user level. Feel free to instruct your users here if they complain about a CMake requirement being set too high. Especially if they want < 3.1 support. Maybe even if they want CMake < 3.15 support...

You can [download CMake from KitWare][cmake-download]. This is how you'll probably get CMake if you are on Windows. It's not a bad way to get it on macOS either, but using `brew install cmake` is much nicer if you use [Homebrew](https://brew.sh) (and you should). You can [download CMake from KitWare][download]. This is how you will probably get CMake if you are on Windows. It's not a bad way to get it on macOS either, but using `brew install cmake` is much nicer if you use [Homebrew](https://brew.sh) (and you should). You can also get it on most other package managers, such as [Chocolaty](https://chocolatey.org) for Windows or [MacPorts](https://www.macports.org) for macOS.
On Linux, there are binaries provided, but you'll need to pick an install location. If you already use `~/.local` for user-space packages, the following single line command[^1] will get CMake for you [^2]: On Linux, there are several options. Kitware provides a [Debian/Ubunutu apt repository][apt], as well as [snap packages][snap]. There are universal Linux binaries provided, but you'll need to pick an install location.
