Local changes don't appear on make'd files

Hello,

I followed through the steps on the Jitsi handbook to get started with developing and making changes to external_api.

I started by adding some Logger.log()'s and after makeing and loading the library into a sample application, I was unable to see the logs. However, after make deving, I was able to see the changes. I’m wondering if there’s a difference between make and make dev in regards to building the version of jitsi on prod instead of the local version?
