Dependency in target.json


I’m trying to extend EFM32GG target for a new board. I has a few sensors and peripherals which are modules. As the target is for the whole board, how can I express that in target.json?

I tried adding “targetDependencies” and “dependencies” properties in target.json, but ‘yt install’ is still not pulling them in (target and modules are currently local, linked and I can get them manually - ‘yt link $MODULE’ & ‘yt install $MODULE’).
