I am writing some C++ project, where OpenGL/glu.h is required from Pangolin library, but can not be found.
I use MacOS 10.14.
I try to find glu.h inside /opt, /usr, /System folders, and indeed I can not find it.
But as I known from OpenGL website, there is no need to install anything on MacOS, so I did not find any installation guide at all.
What could I do to solve this? Thank you.
