ESP-IDF specific REQUIRES list
If you don’t have a REQUIRES list in CMakeLists.txt that is declaring dependencies on certain special components, you typically don’t have to add basic components as REQUIRES also, due to the implicit dependency behaviour of main component (see here).
If you do have a REQUIRES section, you will need to add things like esp_timer, esp_adc, etc components to the REQUIRES list if you are using them, otherwise you will get errors like these:
- fatal error: esp_adc/adc_oneshot.h: No such file or directory
- fatal error: esp_timer.h: No such file or directory
