Linking external *.lib files

[Jolly James via Digitalmars-d-learn]

Let's assume, I have the following 2 dub packages:


pkgBASE:
     (depends on public DUB package)
     source/
     lib/
pkgAPP:
     (depends on pkgBASE)
     source/


I have added pkgBASE via add-path. This wasn't a problem at all.

Unfortunately, the public DUB package requires to be linked with 
the libs from pkgBASE/lib. What do I have to add to pkgBASE's 
dub.json?
