#38350: poppler: subport poppler-quartz
-------------------------+----------------------
 Reporter:  nicos@…      |      Owner:  devans@…
     Type:  enhancement  |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.1.3
 Keywords:               |       Port:  poppler
-------------------------+----------------------
 Several port require poppler to be specifically installed with +qt4
 +quartz variants. This forces users to clean and rebuild with required
 variant, which can be confusing, and breaks compilation from buildbots.

 As a workaround, would it be possible to create a subport poppler-quartz
 within the portfile, which would build a version similar to the
 +qt4+quartz variant which could be referenced as a dependency by ports
 requiring it.

 There is a diff in attachment with a suggestion of subport. As I don't
 have much experience with subports, it should probably get reviewed.

 Ports could then declare a dependency to poppler-quartz if needed, or
 path:/lib/libpoppler.dylib:poppler when either port or subport can be
 employed.
