Feature Description

Fprime libraries set-up include paths and cmake module paths. However, for arbitrary reasons the platform file is loaded first and as such it redoes this work. We should:

1. Load libraries first
2. Use the loaded libraries to then load the platform

This would simplify the code. Minor note: may have issues with collisions.

Deemed not worth the effort. Marking as low priority.
