OpenGL有很多library，在建置環境之前，我們需要了解要下載什麼東西

這邊我們選擇了GLFW + GLAD來建置我們的OpenGL

GLFW 是一個跨平台的OpenGL應用框架，支持窗口創建、讀取輸入和處理事件等功能。特點：輕量級、開源和跨平臺。取代glut 或 freeglut。

GLAD是OpenGL C++的extension library，支援更高級的OpenGL函式。GLAD 可以說是 GLEW的升級版。

可以想成我們安裝了一個GLFW提供了GL的基本函數，而GLAD提供了更進階的GL高級函數。
關於更多的說明可以參考最下面連結[1][2]

實際安裝

下載並安裝visaul studio 2019
Building GLFW
Download GLFW source package https://www.glfw.org/download.html

Download Cmake https://cmake.org/download/

下載後安裝Cmake，開啟Cmake GUI
tool->configure

source選擇好剛剛下載的glfw folder，build的資料夾若沒有就自己創建一個。點擊configure

點擊Generate

點擊Open Project，會自動用VS2019開啟剛剛build好的專案，點選建置方案
我們這邊編譯Debug, x64設定

編譯後的lib會在src/debug裡面

保存所有編譯好的library
先創建資料夾如下，路徑可自行選擇

include 放GLFW裡面的include資料

lib裡面放剛剛的glfw3.lib

開啟新的空白專案

設定include與lib路徑

新增連結器->輸入->其他相依性
if you’re on Windows the OpenGL library opengl32.lib comes with the Microsoft SDK, which is installed by default when you install Visual Studio

配置GLAD
https://glad.dav1d.de/
language C/C++
Profile Core
gl version 3.3 or higher

下載glad.zip

將include資料複製到剛剛創建的include目錄下

glad.c則加入到你的專案裡

Source.cpp加入以下範例程式

#include <glad/glad.h>
#include <glfw3.h>
#include <iostream>
// 設置窗口尺寸
const unsigned int SCR_WIDTH = 400;
const unsigned int SCR_HEIGHT = 300;
#include <glad/glad.h>
#include <glfw3.h>
#include <iostream>
// 設置窗口尺寸
const unsigned int SCR_WIDTH = 400;
const unsigned int SCR_HEIGHT = 300;
int main()
{
    // glfw: 初始化
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
#ifdef __APPLE__
    // uncomment this statement to fix compilation on OS X
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
#endif
    // glfw 創建窗口
    GLFWwindow* window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "Test<GLFW+GLAD>", 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))
    {
        glClearColor(0.0f, 1.f, 0.0f, 1.0f);
        glClear(GL_COLOR_BUFFER_BIT);
        // glfw: swap buffers and poll IO events (keyspressed/released, mouse moved etc.)
        glfwSwapBuffers(window);
        glfwPollEvents();
    }
    // glfw: terminate, clearing all previously allocated GLFWresources.
    glfwTerminate();
    return 0;
}
