How to debug a subproject

[alexqt143]

Hi all,
I have a project with several subprojects.
I can right-click on a subproject and choose run.
But I can not find how to select a specific subproject to be debugged.
(I think I did it on Friday, without changing the active project under project settings, however I can't find it anymore).

Any ideas?

Ah, I found it,
its in the selection on the lower left where you select release / debug.
select build: debug and run: the pro to run.
Then you can just 'start debugging' F5.
