Building with Out-of-Tree Drivers

Hi All,
In order to keep my PX4 code clean and 3rd party for easy reabse, besides the current option to have out-of-tree modules and uORB msgs, I would like to have out-of-tree drivers.
(will be located under my-external-folder/src/drivers)

Would appreciate any help if a solution exists or I need to write one myself :slight_smile:
