I installed IDF v4.4.1 and it seems to work fine. However, I'd like to try the new cdc_acm_vcp example and it seems only to be available in the master branch. So I installed the master branch on top of my existing IDF installation and now I have a frameworks/esp-idf-master folder but when I try to build using this version I get an error saying:

'cmake' must be available on the PATH to use idf.py

The v4.4.1 build works so it seems like cmake must be installed but the master build can't find it. Any idea what might be going wrong? I even tried removing my entire IDF installation and just installing the master branch and that gave the same error.

I think I see the problem. The tools never got setup when I selected the master branch. Selecting it from the Windows start menu produces this error output. Also, I get a popup complaining about not being able to find the python38 dll.
