Issue loading template application in VS Code: wrong CMake kit

[Andrea Verdecchia]

Hi everyone.

I'm approacing to the nrf52833 SoC following this  official tutorial but when I import the example template the VSCode finds the cmake tool in my espressif (ESP32) folder, giving an error about its wrong version:

[variant] Loaded new set of variants

[proc] Executing command: C:\Users\Andrea\.espressif\tools\cmake\3.16.4\bin\cmake.EXE --no-warn-unused-cli -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -Hc:/Users/Andrea/Documents/NordicApps/blinky -Bc:/Users/Andrea/Documents/NordicApps/blinky/build -G "Visual Studio 16 2019" -T host=x64 -A x64

[cmake]   CMake 3.20.0 or higher is required.  You are running version 3.16.4
[cmake]
[cmake]
[cmake] -- Configuring incomplete, errors occurred!

It seems the extension doesn't find the ncs toolchain path. How do I fix the issue?

If you close the work space do you have the pop up to select the Zephyr installation ?

No. If I close the workspace/folder that message doesn't appear.

Today I've unistalled all the Nordic's SDK, Command Line Tool, VS Code extensions, nRF Connect for Desktop, and then I've installed them again following the tutorial I linked above. 

Except for Visial Code that I had already for other my projects with ESP32, Arduino, Flutter and so on...

I've unistalled the Espressiff extension that was not necessary yet and deleted its references in PATH variable. Now when I create a new nRF project from sample I get

Even if I open the VS Code from Nordic Toolchain Manager.
