"CMakeLists.txt not found" when running idf.py

[jonahbron]

I'm running a develop shell directly from the flake ref as in the readme, but when I try to run an idf.py command, I get an error:

$ idf.py erase-flash
Executing action: erase-flash
CMakeLists.txt not found in project directory /home/jonah

Am I missing a step here? FWIW, that path is not a Git repo.

idf.py commands only work in an idf project directory.
