Error during configuration phase of SDK 2.0.0 - cmake version error

[dshadoff]

See issue #38 for an earlier issue during my install which does not appear to be related - this issue happens after restarting and getting past that error.

The tool appears to be reporting that I need CMake 3.17 (see bottom for more detailed output).
However, the pico-sdk README.md states a minimum level of CMake 3.13 is required (and there is no README.md for pico-setup to indicate any minimum requirements) - so at the very least, the documentation of each of the pieces should be updated to reflect actual requirements.

Under the assumption that I just needed to upgrad to 3.17, I tried to upgrade... however, I am not able to obtain a version more recent than CMake 3.16.3 (which I have installed):

$ cmake --version
cmake version 3.16.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

$ sudo apt-get upgrade cmake

For context, I am using a Raspberry Pi 400, and 'uname -a' outputs the following:

$ uname -a
Linux raspberrypi 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux

Here is the output from the install script which indicates the CMake dependency:
