The problem is as follows:

The reason:
Lack of header files and libraries to compile OpenGL;
Solutions:
1. Download OpenGL header files and libraries;
Download address: https://download.csdn.net/download/ssagnn23/2560229
2. Put the file in the specified directory;
(1) Copy GLUX32.DLL, GLUT32.DLL and GLUX.DLL to C:/WINDOWS/system32. The system32 directory should already have OpenGL32.DLL and GLU32.DLL.
(2) Copy Glut. H, Glut. H, Glut. H, Glut. H to
C:/Program Files/Microsoft Visual Studio X.0/VC/include/ GL
Or you might
C:\Program Files (x86)\Microsoft SDKs\Windows\vX.XA\Include\gl
Or you might
C:\Program Files (x86)\Windows Kits\X.X\Include\um\gl

(3) Copy glaux-lib, glu32. LIB, glut32. LIB, opengl32. LIB, Glut.lib, Glut.lib, Glut.lib, Glut.lib, Glut.lib, Glut.lib, Glut.lib
[32Bit]C:/Program Files/Microsoft Visual Studio X.0/VC/lib [32Bit]C:/Program Files/Microsoft Visual Studio X.0/VC/lib
Or you might
C:\Program Files (x86)\Microsoft SDKs\Windows\vX.XA\Lib
Or you might
C:\Program Files (x86)\Windows Kits\X.X\Lib\XXX
