Missing Filters

[supersebbo]

Gr4ffy - firstly, thanks so much for creating this, it's got me 90% of the way to getting CUPS up and running successfully on my router.

I have an issue however, that certain filters needed for my printer are not included in the cups-filters package created from this Makefile. Specifically pdftops - which is the in 'full' cups-filters package available here: https://github.com/OpenPrinting/cups-filters

I am pretty ignorant when it comes to the details of the build system, but how can I update this to include the additional filters needed?

Thank you.
