project_description.json not found while flashing

I've been trying to flash an esp32s3 (Lilygo t-display s3) with the idf.py tool but I'm receiving the following error message;

The sample code from https://docs.espressif.com/projects/esp ... requisites works just fine. Any ideas on what I could be doing wrong?

Kind regards

Have you run "idf.py build" successfully? Maybe check the logs from there first.

I think I found the mistake. I'm trying to build a GUI with the Slint toolkit. Because it showed an include error;

Code: [Select all] [Expand/Collapse]

1. -c /home/user/esp/ui/main/main.cpp
2. /home/user/esp/ui/main/main.cpp:1:10: fatal error: ../build/main.h: No such file or directory

I changed the order of the instructions in CMakeLists so that Slint could generate the missing header first. And while it then actually built (binary was executable), it seems that not the whole build process had actually finished correctly. But now I'm back to the include error mentioned above. Do you see any way around it?

current CMakeLists.txt;
