// 2.  Download glfw from glfw.org/download.html
// 3a. Copy glfw-3.1.bin.WIN32 and glew-1.11.0 libraries to your project directory
// 3b. You can copy glfw-3.1-bin libraries to your project directory add the src files and compile
// 4.  Configure project property for the include and lib files

int main()
{
    if (!glfwInit()) {
        fprintf(stderr, "ERROR: could not start GLFW3\n");
        return 1;
    }

    GLFWwindow* window = glfwCreateWindow(640, 480, "OpenGL - Window Title", NULL, NULL);
    if (!window) {
        fprintf(stderr, "ERROR: could not open window with GLFW3\n");
        glfwTerminate();
        return 1;
    }

    glfwMakeContextCurrent(window);

    GLenum err = glewInit();
    if (err != GLEW_OK) {
        fprintf(stderr, "Error: %s\n", glewGetErrorString(err));
    }

    glClearColor(0.6f, 0.6f, 0.8f, 1.0f);

    while (!glfwWindowShouldClose(window)) {
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
        glfwPollEvents();
        glfwSwapBuffers(window);
    }

    glfwTerminate();
