openglGL 环境搭建

1、

下载我搞好的包：glad 、glfw 、glew

2 、

在vstdio新建一个空项目，之后右击项目名字，选择属性

选择VC++目录、包含目录

添加包中头文件目录，根据自己实际情况添加。

选择VC++目录、库目录

添加库文件目录，根据自己实际目录添加,l我选择的是ib-vc2015这个目录，如果你的vs版本低，就选择对应的就可以啦。

3 、

找到属性、连接器、输入、附加依赖项

opengl32.lib
glfw3.lib
glew32s.lib

下面的忽略特定默认库写上

MSVCRT.lib

4 、

添加glad.c文件，这个在下载包中可以找到

之后在新建一个main.c放我们测试代码

5 、测试代码
