Q:

trouble trying to build opengl superbible example code

So I got the superbible 6th edition, and am trying to cmake and make the example code framework, but get this error:

What am I missing? As far as I can tell I have all the dependencies installed already.

A:

There is a bug in CMakeLists.txt at line 13.
(https://github.com/openglsuperbible/sb6code/blob/master/CMakeLists.txt)
Change "elif (UNIX)" to "elseif (UNIX)",and it will be ok.
