Building C++ program with i2c-dev lib

Question

I have been trying to build a C++ program using the i2c-dev.h library on Ubuntu Core 22.04.02 LTS, so I can read and write I2C packets. But I can't get my program to build correctly. I tried including the path in my makefile but the compiler returns errors from what appears to be compiling some of the Linux headers themselves.

Here is my makefile now:

CC = g++
CFLAGS = -Wall
ALL_LIBS = -lrt -lstdc++ -std=c++11 -pthread -L/opt/picoscope/lib -lps4000a -libi2c
INCLUDES = -I/opt/picoscope/include/libps4000a -I/usr/src/linux-headers-5.15.0-67-generic/include -I/usr/src/linux-headers-5.15.0-67-generic/arch/x86/include/generated
ALL_TARGET = verde
all: $(ALL_TARGET)
$(ALL_TARGET): verde.cpp verde.h
    $(CC) -o $(ALL_TARGET) verde.cpp $(CFLAGS) $(ALL_LIBS) $(INCLUDES)
clean: 
    rm -f .o
    rm -f $(ALL_TARGET)
    rm -f .bin
    rm -f .csv
    rm -f .txt
    sudo rm -rf CPU*
    sudo rm -rf RF*

Here is the latest error message when running make:
