Converting Makefile to CMake with local includes and libs - gcc

Question

I am unsure of how to add my include and libs files to a cmake file. I keep seeing references to several methods that I do not understand when trying to figure this out. I need to get my /include and /lib directories into CMake properly so I can use them in my code. What is the proper way of adding libraries to CMake?
OBJS = simple.o
INCLUDES = -I../../include
LIBS = -L../../lib
LDFLAGS = -lglad -lglfw3
PROGRAM = simple
CFLAGS = -g
COMPILER = g++
ifeq ($(OS),Windows_NT) # is Windows_NT on XP, 2000, 7, Vista, 10...
LDFLAGS += -lopengl32 -lgdi32
PROGRAM :=$(addsuffix .exe,$(PROGRAM))
else ifeq ($(shell uname -s),Darwin) # is MACOSX
LDFLAGS += -framework Cocoa -framework OpenGL -framework IOKit
endif
simple: clean $(OBJS)
$(COMPILER) -o $(PROGRAM) $(OBJS) $(LIBS) $(LDFLAGS)
simple.o: simple.c
$(COMPILER) $(INCLUDES) $(CFLAGS) -c simple.c
RM = rm -f
ifeq ($(OS),Windows_NT) # is Windows_NT on XP, 2000, 7, Vista, 10...
RM := del
endif
clean:
$(RM) $(OBJS) $(PROGRAM)
This is all I've got so far:
cmake_minimum_required(VERSION 3.23)
project(hw2)
set(CMAKE_CXX_STANDARD 17)
add_library(bar SHARED IMPORTED)
add_executable(hw2 main.cpp)

Answer 1

A simple example for you:
The files in this example are below:
tree
.
├── CMakeLists.txt
├── include
│   └── shared
│   └── Hello.h
└── src
├── Hello.cpp
└── main.cpp
CMakeLists.txt[] - Contains the CMake commands you wish to run
include/shared/Hello.h[] - The header file to include
src/Hello.cpp[] - A source file to compile
src/main.cpp[] - The source file with main
STEP 1: Specify the minimum version of CMake and create a project
cmake_minimum_required(VERSION 3.5)
project(hello_library)
STEP 2: Add a Shared Library using add_library
add_library(hello_library SHARED
src/Hello.cpp
)
STEP 3: Set the directories that should be included using target_include_directories
target_include_directories(hello_library
PUBLIC
${PROJECT_SOURCE_DIR}/include
)
STEP 4: Add an executable
add_executable(hello_binary
src/main.cpp
)
STEP 5: Link a Shared Library using target_link_libraries
target_link_libraries( hello_binary
PRIVATE
hello_library
)
