一、环境

Windows 10 64位家庭版
vs版本：Visual Studio 2017

二、配置OpenGL所需

GLFW
GLAD

三、步骤

1.配置GLFW

进入官网下载GLFW并解压：GLFW下载
这里选择32位的，因为64位的可能有些问题
进入VS2017创建空项目，在项目文件夹下创建includes和libs两个文件夹（如创建项目OpenGL，则为OpenGL/OpenGL/includes）
将解压文件中lib-vc2017文件夹下的.lib文件拷贝进刚刚创建的libs下，同时将include下的.h文件拷贝进刚刚创建的includes下
在项目名处右键->属性->VC++目录->引用目录->编辑：粘贴项目文件夹下的.h文件所在目录
同理，库目录->编辑：粘贴项目文件夹下的.lib文件所在目录
接着将为项目添加依赖项：仍然是属性->链接器->输入->附加依赖项->编辑，将opengl32.lib，glfw3.lib，msvcrt.lib添加进去

2.GLAD

进入GLAD官网：GLAD下载
Language选C\C++，Profile选core，version根据需要选择（3.3版本及以上），然后GRNERATE，之后选择zip文件下载并解压
将include下的.h文件全部拷贝进项目文件夹下的includes下，将src下的glad.c拷贝进项目文件夹下
然后进入vs，添加源文件->现有项，将glad.c添加进项目
至此库文件配置完成，接下来测试是否能正常使用OpenGL

3.测试OpenGL

创建源文件，首先需要引用glad.h和glfw3.h文件

因为使用的是自己添加的文件，这里引用需要使用“ “而非<>，使用” “时，它会自动出现你所添加的目录

#include"includes/glad.h"
#include"includes/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);
    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);

    // 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);
        // glfw: swap buffers and poll IO events (keys pressed/released, mouse moved etc.)
        // -------------------------------------------------------------------------------
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    // glfw: terminate, clearing all previously allocated GLFW resources. 
    // ------------------------------------------------------------------ 
    glfwTerminate(); 
    return 0; 
} 
// process all input: query GLFW whether relevant keys are pressed/released this frame and react accordingly 
// --------------------------------------------------------------------------------------------------------- 
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); 
}
