Download the GLUT libraries via this link:
http://avida.cs.wright.edu/courses/CEG476/glut-3.7.6-bin.zip

Copy the GLUT files from the zip archive to the following directories:
glut.h: C:\Program Files\Microsoft SDKs\Windows\v10.0A\Include\gl
glut.lib: C:\Program Files\Microsoft SDKs\Windows\v10.0A\Lib
glut32.dll: C:\WINDOWS\system32

For other versions of Windows, you can simply copy the files into the
corresponding directories for the SDK version you have installed, e.g.
v8.1 or v7.0A.

Make sure your IDE, e.g. Visual Studio, knows the paths to the header file
and library. In Visual Studio, this can be done in the properties dialog
for your project under the compiler and linker settings.
