Build process is complex

Hi @mkiol

I'm continuing my works on Speech Note. One of my biggest challenge is it's very long to build the project. It is also complex due to the amount of statically linked dependencies (gh#206)

Do you have plans for a simpler build process, or a more flexible "plugin/add-on" system?

For my personal needs, I will try to implement a CLI-based build with optional model support. That should be much faster to test, any special need you would have for a MR in that direction?
