Unresolved inclusion. unless it was included in "app_main.c". (IEP-1206)

[SirPumpkin797]

Describe the bug
I have created one project from Espress IDF Project SPI_Slave_Receive and modified it by adding DEFINE.h Extern_Vars.h Global_Vars.c HW_Setup.h SPI.h SPI.c Wifi.h Wifi.c.

All inclusions that refers to common libraries like "stdio.h" "esp_wifi.h" are not able to be resolved, unless it was included in file "app_main.c". (for example in DEFINE.H).

To Reproduce

1. create header file like "DEFINE.H"
2. include "DEFINE.H" in app_main.c
3. include all inclusions in "DEFINE.H" instead of in app_main.c
4. see erros.
   Expected behavior
