Setting up SDL_mixer 3.0.0 in Visual Studio 2022 using CMake

• Install SDL 3.1.10 using this guide: How to install SDL 3.1.10 using CMake and Visual Studio 2022 for Desktop
• Install SDL_mixer 3.0.0 using this guide: How to install SDL_mixer 3.0.0 using CMake and Visual Studio 2022 for Desktop
• Run Visual Studio
• Click on the "Create a new project" button:

• Click on the "CMake Project" and click on the "Next" button:

• Type a project name, set a project location, check the "Place solution and project in the same directory" checkbox, and click on the "Create" button:

• Wait a few seconds for configuration
• Run the project by click on the empty green triangle (or Ctrl+F5):

• The program prints "Hello CMake" to the console:

• Double click on the "CMakePresets.json" file:

• Add the "SDL3_DIR" and "SDL3_mixer_DIR" variables with the following "value" and "type" for "Debug":

        {
            "name": "x64-debug",
            "displayName": "x64 Debug",
            "inherits": "windows-base",
            "architecture": {
                "value": "x64",
                "strategy": "external"
            },
            "cacheVariables": {
                "CMAKE_BUILD_TYPE": "Debug",
                "SDL3_DIR": {
                    "value": "E:/libs/sdl-3.1.10-msvc/win/debug/cmake",
                    "type": "PATH"
                },
                "SDL3_mixer_DIR": {
                    "value": "E:/libs/sdl3_mixer-3.0.0-msvc/win/debug/cmake",
                    "type": "PATH"
                }
            }
        },

• Make the same for "Release":

        {
            "name": "x64-release",
            "displayName": "x64 Release",
            "inherits": "x64-debug",
            "cacheVariables": {
                "CMAKE_BUILD_TYPE": "Release",
                "SDL3_DIR": {
                    "value": "E:/libs/sdl-3.1.10-msvc/win/release/cmake",
                    "type": "PATH"
                },
                "SDL3_mixer_DIR": {
                    "value": "E:/libs/sdl3_mixer-3.0.0-msvc/win/release/cmake",
                    "type": "PATH"
                }
            }
        },

• Double click on the "CMakeLists.txt" file:

• Add this code to the "CMakeLists.txt" file

# Copy the assets folder to the dist folder
add_custom_command(TARGET hello-sdl3-mixer POST_BUILD
    COMMAND ${CMAKE_COMMAND} -E copy_directory
    ${CMAKE_SOURCE_DIR}/assets $<TARGET_FILE_DIR:hello-sdl3-mixer>/assets)

find_package(SDL3)
find_package(SDL3_mixer)

• Download the "picked-coin-echo-2.wav" here and place it to the "assets/audio" folder
• Replace the "hello-sdl3-mixer.cpp" file content with this one:

    } else if (event->type == SDL_EVENT_MOUSE_BUTTON_DOWN) {

    }
    return SDL_APP_CONTINUE; // Carry on with the program
}

// This function runs once per frame, and is the heart of the program
SDL_AppResult SDL_AppIterate(void *appstate)
{
    // Clear the screen
    SDL_SetRenderDrawColor(renderer, 0, 0, 0, 255);
    SDL_RenderClear(renderer);

    // Update the screen
    SDL_RenderPresent(renderer);
    return SDL_APP_CONTINUE; // Carry on with the program
}

// This function runs once at shutdown
void SDL_AppQuit(void *appstate, SDL_AppResult result)
{
    // SDL will clean up the window/renderer for us
    if (g_wave) {
