# Add the raylib package via vcpkg
find_package(raylib CONFIG REQUIRED)

# Add the executable
add_executable(RaylibExample main.cpp)

# Link Raylib
target_link_libraries(RaylibExample PRIVATE raylib::raylib)

This configuration does the following:

Sets the C++ standard to C++17.
Finds the Raylib package installed by vcpkg.
Links the Raylib library to your project.

Step 5: Write the Code

Now, let’s create a simple C++ program that initializes a window and draws a rectangle that you can move around with the arrow keys. Create a main.cpp file with the following content:

#include <raylib.h>

int main() {
    // Initialize the window
    InitWindow(800, 600, "Raylib Example");

    // Define the rectangle
    Rectangle rect = { 350, 250, 100, 100 };
    int speed = 5;

    // Main game loop
    while (!WindowShouldClose()) {
        // Move the rectangle with arrow keys
        if (IsKeyDown(KEY_RIGHT)) rect.x += speed;
        if (IsKeyDown(KEY_LEFT)) rect.x -= speed;
        if (IsKeyDown(KEY_DOWN)) rect.y += speed;
        if (IsKeyDown(KEY_UP)) rect.y -= speed;

        // Start drawing
        BeginDrawing();

        ClearBackground(RAYWHITE);

        // Draw the rectangle
        DrawRectangleRec(rect, BLUE);

        DrawText("Move the rectangle with arrow keys", 10, 10, 20, DARKGRAY);

        // End drawing
        EndDrawing();
    }

    // Close the window
    CloseWindow();

    return 0;
}

Step 6: Build and Run the Project

Build the Project: In CLion, click on the build button or press Ctrl + F9 to build your project.
Run the Project: After building, run the project with Shift + F10 or by clicking the run button.

When you run the program, you should see a window open with a rectangle in the center. You can move the rectangle around using the arrow keys.

Conclusion

By following these steps, you’ve set up a simple C++ project using Raylib in CLion with minimal effort. With vcpkg handling the dependencies and CMake managing the build process, you can focus on coding your game or multimedia project without worrying about complex configurations.
