fatal error: GLUT/freeglut.h file not found Catalina

问题

I am using

#include <gl/freeglut.h>

but getting

"fatal error: GLUT/freeglut.h file not found"

** I tried reinstall "brew install glew freeglut" and also "

#ifdef __APPLE__ 
#include <OpenGL/gl.h> 
#include <GLUT/glut.h> 
#else 
#include <GL/gl.h> 
#include <GL/glut.h>
#endif"

I also tried:

#include <GL/freeglut.h>

but none of them worked...
