Setting up SDL2 in macOS (Xcode or CMake)

Setting up SDL2 with CMake in CLion

How do I configure an SDL2 project using CMake in the CLion IDE?

CLion is a popular cross-platform IDE that uses CMake as its build system. To set up an SDL2 project in CLion:

  1. Create a new C++ project and select "CMake" as the build system.
  2. Open the CMakeLists.txt file and add the SDL2 configuration:
cmake_minimum_required(VERSION 3.16)
project(MyProject)

set(CMAKE_CXX_STANDARD 20)

find_package(SDL2 REQUIRED)
find_package(SDL2_image REQUIRED)
find_package(SDL2_ttf REQUIRED)

add_executable(MyProject main.cpp)

target_link_libraries(
  MyProject
  SDL2::SDL2
  SDL2::SDL2_image
  SDL2::SDL2_ttf
)

Step 1: Create a main.cpp file and add a simple SDL2 test program:

#include <SDL.h>
#include <SDL_image.h>
#include <SDL_ttf.h>

#include <iostream>

int main(int argc, char** argv) {
  if (SDL_Init(SDL_INIT_VIDEO) != 0) {
    std::cout << "SDL_Init Error: "
      << SDL_GetError() << std::endl;
    return 1;
  }

  std::cout << "SDL2 initialized successfully!"
    << std::endl;

  SDL_Quit();
  return 0;
}

Step 2: Build and run the project. If you see the "SDL2 initialized successfully!" message, your setup is complete!

Note: Make sure you have installed SDL2, SDL2_image, and SDL2_ttf on your system and that CMake can find them. You may need to set the SDL2_DIR, SDL2_IMAGE_DIR, and SDL2_TTF_DIR environment variables to point to the correct locations.
