Steps

1. Install brew:
   "/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. brew install sdl2
brew install sdl2_image
brew install sdl2_ttf

3. Open the project file terminal

4. Create project layout: mkdir -p build/debug include lib src

5. Finding the location of the sdl2:
   brew list sdl2
brew list sdl2_image
brew list sdl2_ttf

6. My location of files:

   SDL2

   /opt/homebrew/Cellar/sdl2/2.30.0/bin/sdl2-config
   /opt/homebrew/Cellar/sdl2/2.30.0/include/SDL2/ (78 files)
   /opt/homebrew/Cellar/sdl2/2.30.0/lib/libSDL2-2.0.0.dylib
   /opt/homebrew/Cellar/sdl2/2.30.0/lib/cmake/ (2 files)
   /opt/homebrew/Cellar/sdl2/2.30.0/lib/pkgconfig/sdl2.pc
   /opt/homebrew/Cellar/sdl2/2.30.0/lib/ (4 other files)
   /opt/homebrew/Cellar/sdl2/2.30.0/share/aclocal/sdl2.m4
   

   SDL2_image

   /opt/homebrew/Cellar/sdl2_image/2.8.2/include/SDL2/SDL_image.h
   /opt/homebrew/Cellar/sdl2_image/2.8.2/lib/libSDL2_image-2.0.0.dylib
   /opt/homebrew/Cellar/sdl2_image/2.8.2/lib/cmake/ (2 files)
   /opt/homebrew/Cellar/sdl2_image/2.8.2/lib/pkgconfig/SDL2_image.pc
   /opt/homebrew/Cellar/sdl2_image/2.8.2/lib/ (2 other files)
   

   SDL2_ttf

   /opt/homebrew/Cellar/sdl2_ttf/2.22.0/include/SDL2/SDL_ttf.h
   /opt/homebrew/Cellar/sdl2_ttf/2.22.0/lib/libSDL2_ttf-2.0.0.dylib
   /opt/homebrew/Cellar/sdl2_ttf/2.22.0/lib/cmake/ (2 files)
   /opt/homebrew/Cellar/sdl2_ttf/2.22.0/lib/pkgconfig/SDL2_ttf.pc
   /opt/homebrew/Cellar/sdl2_ttf/2.22.0/lib/ (2 other files)
   

7. Linking sdl2 files:

   SDL2

   into include: ln -s /opt/homebrew/Cellar/sdl2/2.30.0/include/SDL2 ./include/SDL2
   into lib: ln -s /opt/homebrew/Cellar/sdl2/2.30.0/lib ./lib/SDL2

   SDL2_image

   into include: ln -s /opt/homebrew/Cellar/sdl2_image/2.8.2/include/SDL2 ./include/SDL2_image
   into lib: ln -s /opt/homebrew/Cellar/sdl2_image/2.8.2/lib ./lib/SDL2_image

   SDL2_ttf

   into include: ln -s /opt/homebrew/Cellar/sdl2_ttf/2.22.0/include/SDL2 ./include/SDL2_ttf
   into lib: ln -s /opt/homebrew/Cellar/sdl2_ttf/2.22.0/lib ./lib/SDL2_ttf

8. Create main.pp and Makefile:

   touch src/main.cpp
   touch Makefile
   

9. Code for Makefile

   SRC_DIR = src
   BUILD_DIR = build/debug
   CC = g++
   SRC_FILES = $(wildcard $(SRC_DIR)/*.cpp)
   OBJ_NAME = play
   INCLUDE_PATHS = -I include/SDL2 -I include/SDL2_image -I include/SDL2_ttf
   LIBRARY_PATHS = -L lib/SDL2 -L lib/SDL2_image -L lib/SDL2_ttf
   COMPILER_FLAGS = -std=c++11 -Wall -O0 -g
   LINKER_FLAGS = -lSDL2 -lSDL2_image -lSDL2_ttf
   
   all:
       $(CC) $(COMPILER_FLAGS) $(LINKER_FLAGS) $(INCLUDE_PATHS) $(LIBRARY_PATHS) $(SRC_FILES) -o $(BUILD_DIR)/$(OBJ_NAME)

10. Code for main.cpp

    #include <SDL.h>
    #include <iostream>
    
    int main() {
        std::cout << "Hello, SDL!" << std::endl;
    
        // Initialize SDL
        if (SDL_Init(SDL_INIT_VIDEO) != 0) {
            std::cerr << "SDL_Init Error: " << SDL_GetError() << std::endl;
            return 1;
        }
    
        // Create a window
        SDL_Window* window = SDL_CreateWindow("SDL Window", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_SHOWN | SDL_WINDOW_RESIZABLE);
        if (window == nullptr) {
            std::cerr << "SDL_CreateWindow Error: " << SDL_GetError() << std::endl;
            SDL_Quit();
            return 1;
        }
    
        // Create a renderer
        SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
        if (renderer == nullptr) {
            std::cerr << "SDL_CreateRenderer Error: " << SDL_GetError() << std::endl;
            SDL_DestroyWindow(window);
            SDL_Quit();
            return 1;
        }
    
        SDL_Event e;
        bool quit = false;
        while (!quit){
            while (SDL_PollEvent(&e)){
                if (e.type == SDL_QUIT){
                    quit = true;
                }
                if (e.type == SDL_KEYDOWN){
                    quit = true;
                }
                if (e.type == SDL_MOUSEBUTTONDOWN){
                    quit = true;
                }
            }
            // Set render color to blue
            SDL_SetRenderDrawColor(renderer, 255, 255, 255, 255);
    
            // Clear the window with the render color
            SDL_RenderClear(renderer);
    
            // Update the screen
            SDL_RenderPresent(renderer);
        }
    
        // Clean up resources
        SDL_DestroyRenderer(renderer);
        SDL_DestroyWindow(window);
        SDL_Quit();
    
        return 0;
    }

11. Test:
    make
.\build\debug\play

If you have white window on your screen everything is set.
