Packaging cvfind in OBS for Debian and Ubuntu

[Bob-O-Rama]

I have cvfind checked into OBS. This was based on this repo being closed and having to fetch the sources with authentication. I'd like to get a proper OBS setup which pulls the zipball from git and builds against any compatible distributions. So the ask is either clone what I did and construct a compatible description file ( using the source tarball in OBS ) to build against debian and ubuntu - and just take over the packaging, Or work out the description files and I'll merge that back into my OBS project. The latter is just a one-off without any long term expectations.
