visual studio配置opengl

# 前言

本来想配置vs code的，结果opengl在mingw64上安装出了蛮多问题，比如下载的二进制包是32位的，用32位的mingw64编译完cpp代码后提示缺ddl，网上说要下qt；自己编译64位的，在cmake后面没编译出来（）

最终因为技术不足已老实，现在开始用笨重的紫色vs（）

安装选择桌面cpp开发

新建一个控制台项目，确保可以输出hello world

下载64位编译好的

include的解压放到

`D:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.41.34120\include`

lib-vc2022的解压放到

`D:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.41.34120\lib\x64`

项目->属性->连接器->输入->附加依赖项

`$(CoreLibraryDependencies);%(AdditionalDependencies)`

改为

`opengl32.lib;glfw3.lib;$(CoreLibraryDependencies);%(AdditionalDependencies)`

测试运行

```c++
#include <GLFW/glfw3.h>

int main(void)
{
	GLFWwindow* window;

/* Initialize the library */
	if (!glfwInit())
		return -1;

/* Create a windowed mode window and its OpenGL context */
	window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
	if (!window)
	{
		glfwTerminate();
		return -1;
	}

/* Make the window's context current */
	glfwMakeContextCurrent(window);

/* Loop until the user closes the window */
	while (!glfwWindowShouldClose(window))
	{
		/* Render here */
		glClear(GL_COLOR_BUFFER_BIT);

glBegin(GL_TRIANGLES);
		glVertex2d(0.5f, 0.5f);
		glVertex2d(-0.5f, -0.5f);
		glVertex2d(0.5f, -0.5f);

glEnd();

/* Swap front and back buffers */
		glfwSwapBuffers(window);

/* Poll for and process events */
		glfwPollEvents();
	}

glfwTerminate();
	return 0;
}
```

弹出三角形则成功
