c++ - 如何修复 "unresolved external symbol _gladLoadGLLoader referenced in function _main"和 "unresolved external symbol _glad_glViewport"？

Question

我在构建程序时不断收到“未解析的外部符号”错误。但是，该程序编译正常。我正在使用 GLFW 和 GLAD 库。

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

#include <iostream>

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

//#undef main
int main() {
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    GLFWwindow* window = glfwCreateWindow(800, 600, "LearningOpenGL", NULL, NULL);

    if (window == NULL) {
        std::cout << "Failed To Create Window" << std::endl;
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);

    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);

    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress)) {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }

    while (!glfwWindowShouldClose(window))
    {
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    glViewport(0, 0, 800, 600);

    glfwTerminate();
    return 0;
}

void framebuffer_size_callback(GLFWwindow* window, int width, int height) {
    glViewport(0, 0, width, height);
}

我不断收到同样的 2 个错误:

Main.obj : error LNK2019: unresolved external symbol _gladLoadGLLoader referenced in function _main

Main.obj : error LNK2001: unresolved external symbol _glad_glViewport

转到项目名称 -> 添加 -> 现有项目，然后添加 glad.c
