<EEPROM.h> no such file or directory

I created arduino project with PlatformIO but I cannot use built-in arduino libraries such as EEPROM.h, SoftwareSerial.h etc. I can only use Arduino.h. How can I include them ?

anyone who has an idea ?

Just include them via #include <EEPROM.h>, etc. PlatformIO will find and built libraries automatically.
