I installed OpenGL onto my computer running Linux Mint following the instructions on this tutorial. I am trying to compile a program that uses OpenGL, but I'm getting a compile error: fatal error: GL/glew.h: No such file or directory. I check the /usr/include/GL folder, and glew.h is indeed missing. I don't know why it's missing, because I did the command sudo apt-get install libglew1.5 and it gives the output:
Reading package lists... Done

libglew1.5 is already the newest version.

Why is the glew.h file missing?
libglew is just the library, but not the development files (headers). You need to install those separately. The package name on Debian based systems is libglew-dev
and for fedora(and possibly its derivatives) it is glew-devel
