Hi @njacazio, what is the problem you are trying to solve here?

[njacazio]

Ciao @mpuccio no problem actually. Thanks to the recent feature of the selection of the installed target I wanted to split the compilation of core filtering from the user tasks. This is still a draft as you see. If you find it useful we can go on.

@njacazio, I see, for this I would see it useful only to decouple Zorro from the rest, but I would not split the various PWG as for maintaining the EventFiltering we want to have all the filters available without knowing which PWG we should manually enable. I can take care of the decoupling of Zorro, but I would not go further with the rest of the PWG decoupling.

Hi, sounds good, please go ahead!
