Oculus Mobile SDK Native Apps - build.py process

Hello,

I am using the Oculus Mobile SDK for native apps and I am trying to add a third-party library to the build process. I do not fully understand all the moving parts that happen once I run build.py. Does anyone have any good resources describing the setup/architecture? I've tried reverse engineering, but it's pretty dense. I'd appreciate any help/advice/direction/references/ramblings. 

Thanks!
