Bug#925540: qhull: add libqhullcpp to installed libraries

[Barak A. Pearlmutter]

Ah right, transition, experimental, oops.
Just uploaded to experimental.

Please feel free to upload yourselves next time; certainly anyone on
the science team, etc. Jochen, do you want to officially co-maintain
or whatever? The repo is under science-team for a reason, but I'm
happy to give additional access rights if necessary.

Cheers,

--Barak.
