Zephyr https://github.com/zephyrproject-rtos/zephyr/tree/main now requires CMake version 3.20 or newer.

The docs has been updated with info on how to do this on systems that has an older CMake per default:
https://docs.zephyrproject.org/latest/getting_started/index.html#install-dependencies

For Ubuntu users, an easy guide is found here:
https://apt.kitware.com/

The main reason for increasing CMake version is better toolchain
support.
The decision to bump the CMake version was taken by the Toolchain WG.

Better toolchain support is added in the following CMake versions:

• armclang, CMake 3.15
• Intel oneAPI, CMake 3.20
• IAR, CMake 3.15 and 3.20
