Hi - I am battling to get a clear cut answer on what the approach is to build a private package (not 2GP unlocked) that is dependent on NPSP.   I understand that CCI handles all the dependencies etc but how does this actually work once a package is created?  Does the NPSP metadata actually "live" as part my package or is it purely for packaging purposes and when installing in a client using the standard package install screen, then do they need to have NPSP already installed?  Hope this makes sense...
