CMake: Compiling Libraries step by step

So for a while now I've been trying to get the JBEngine cross compiling using CMake. I started this off by creating cross platform versions of the most simple libraries first, Maths and Sound. This was easy because they had very few dependencies and hardly and source code.

I have currently managed to build all the libraries, which are:

• ​Maths
• Sound
• Networking
• Physics
• ​Renderer
  
• Awesomium/GUI
• JBEngine

When I have now come to put all this together and compile the Space Invaders executable it has become a nightmare.

​There are just too many errors!

Taking a step back

To overcome the sheer amount of issues I have decided to create small test applications with minimal parts of the JBEngine libraries. That way I can narrow down issues, to specific libraries. This is something I had done a while back to check that the Sound library worked. I created an application that loads one sound and plays it on repeat.

Last night I found a tutorial online that uses CMake with glfw, glew and assimp so I managed to get those working nicely. Here is a list of test applications I will make in order:

• ​Window Creation (openGL, glfw, glew)
• Window with fullscreen texture (SOIL)
• Window with single loaded mesh (assimp)

For now this will do, as I'm not sure exactly which libraries will cause the problems.

​I will be separating out the window creation into another library as that seems to make sense. The JBEngine library has become far too bloated, and it will make these test applications easier to create.

Finally I am hoping that by building these test applications, not only will I create a better architecture but I will also keep motivation high. Each little test application can be thought of as a milestone which will be rewarding on completion.

Thanks :)
