Esp32 project - can't find needed headers


I am new to the world of embedded programming. I have an esp-32s3 that I am progrmaming to connect to wifi and create a server to stream data onto. In my main file, i have
"#include “protocol_examples_common.h”

#include <esp_https_server.h>

however, when i try to build, the terminal states that
src/main.c:492:10: fatal error: protocol_examples_common.h: No such file or directory

I can indeed locate these two files within the folder in my C drive, so I am not usre why this error comes. How can I fix this please?
