Como hago para incluir GLAD y GLFW3 en c++ y que no me salgan errores como:

undefined reference to `glfwInit'
undefined reference to `glfwWindowHint'
undefined reference to `glfwWindowHint'
undefined reference to `glfwWindowHint'
undefined reference to `glfwCreateWindow'
undefined reference to `glfwTerminate'
undefined reference to `glfwMakeContextCurrent'
undefined reference to `gladLoadGLLoader'
undefined reference to `glfwWindowShouldClose'
undefined reference to `glfwSwapBuffers'
undefined reference to `glfwPollEvents'
undefined reference to `glfwTerminate'

este es mi codigo (viene de https://github.com/vkphillia/opengl-cpp-template):

#include <glad/glad.h>
#include <GLFW/glfw3.h>
#include <iostream>

void framebuffer_size_callback(GLFWwindow *window, int width, int height);
void processInput(GLFWwindow *window);

// settings
const unsigned int SCR_WIDTH = 800;
const unsigned int SCR_HEIGHT = 600;
int main()
{
    // glfw: initialize and configure
    // ------------------------------
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
#ifdef __APPLE__
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE); //uncomment this statement to fix compilation on OS X
#endif
    // glfw window creation
    // --------------------
    GLFWwindow *window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "LearnOpenGL", NULL, NULL);
    if (window == NULL)
    {
        std::cout << "Failed to create GLFW window" << std::endl;
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);
    // glad: load all OpenGL function pointers
    // ---------------------------------------
    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
    {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }
    // render loop
    // -----------
    while (!glfwWindowShouldClose(window))
    {
        // input

        processInput(window);

        // render

        // glClearColor(0.2f, 0.3f, 0.3f, 1.0f);
        glClear(GL_COLOR_BUFFER_BIT);

        // glfw: swap buffers and poll IO events (keys pressed/released, mouse moved etc.)
        // -------------------------------------------------------------------------------
        glfwSwapBuffers(window);
        glfwPollEvents();
    }
    // glfw: terminate, clearing all previously allocated GLFWresources.
    //---------------------------------------------------------------
    glfwTerminate();
    return 0;
}

void processInput(GLFWwindow *window)
{
    if (glfwGetKey(window, GLFW_KEY_ESCAPE) == GLFW_PRESS)
        glfwSetWindowShouldClose(window, true);
}

// glfw: whenever the window size changed (by OS or user resize) this callback function executes
// ---------------------------------------------------------------------------------------------
void framebuffer_size_callback(GLFWwindow *window, int width, int height)
{
    // make sure the viewport matches the new window dimensions; note that width and
    // height will be significantly larger than specified on retina displays.
    glViewport(0, 0, width, height);
}

He leido la documentación en el sitio web de GLFW y también intenté buscar soluciones en YouTube.
