Description
I want to start using the project in vendored mode and add our own custom PHP extension. This means we should add additional 'sources' and 'ext' items to have a streamlined process with the project.
Is this already possible to achief? If so could you guide me a little or point me in a direction?
After digging around I think we need to add additional configuration into the BuilderPovider
instance. I coulnd't find a proper way yet to add the addional configuration yet.
