在arduino项目中使用ArduinoCore avr库

我想在我的项目中使用ArduinoCore avr。我不想使用arduino的IDE默认函数setup((和loop((。我也不想使用arduino的IDE来编译十六进制文件并将其刻录到我的设备中。ArduinoCore avr库从ArduinoCore下载
硬件：arduino uno(atmega328p(
目录结构：
/ArduinoCore avr/cores/arduino/arduino.h
./main.c
../Makefile

main.c:

#ifndef F_CPU
#define F_CPU 16000000UL // or whatever may be your frequency
#endif
#include <avr/io.h>
#include <util/delay.h>                // for _delay_ms()
#include "ArduinoCore-avr/cores/arduino/Arduino.h" // This line gave me error.
#define LED_PIN 13
int main(void)
{
DDRB=0b11100000;//pin 13 is in output mode
while (1) {
PORTB=0b11100000; //make pin 13 high and power on the led
_delay_ms(1000);
PORTB=0b11000000; //make pin 13 low and power off the led
_delay_ms(1000);
}
}

# DEVICE ....... The AVR device you compile for

# OBJECTS ...... The object files created from your source files. This list is

# PROGRAMMER ... Options to avrdude which define the hardware you use for
#                uploading to the AVR and the interface where this hardware
#                is connected.
# FUSES ........ Parameters for avrdude to flash the fuses appropriately.

$(COMPILE) -E main.c

使用以下命令进行编译时
make
它显示以下错误。

In file included from main.c:7:
ArduinoCore-avr/cores/arduino/Arduino.h:257:10: fatal error: pins_arduino.h: No such file or directory
#include "pins_arduino.h"
^~~~~~~~~~~~~~~~
compilation terminated.

1. 我知道我必须在Makefile中添加库，但我不知道如何做到这一点
2. 在main.c中包含头文件时，我应该使用#include "ArduinoCore-avr/cores/arduino/Arduino.h"还是#include "Arduino.h"
3. 我之所以要包含Arduino.h文件，是因为我想在main.c中使用pinMode和digitalWrite函数。我不想重新发明轮子(从头开始写驱动程序(。这可能吗？我试图搜索示例代码，但它们都使用arduino的默认函数loop和setup，这是我想要避免的

谢谢。
