As far as I know it has always been this way.

I think it is sensible that the definition of a target is scoped to one 
single directory.
Where the definition of a target consists of e.g. sources, properties, 
dependencies and custom commands related to the target.

You can reference/query global targets in other directories but you can 
not change them.
