As the log is saying
--   package 'cairo>=1.10.0' not found

Well, you are the user of the API, what would you like to have?

I can tell you what i'd like from the Qt frontend perspective. We already have 
the concept of Converter[1] from which we have the PDF[2] and PS[3] converters 
that have a set of options you can pass, so something similar for SVG 
conversion would for sure make sense.

A pdf to abiword converter used by the commandling pdftoabw tool (that i will 
propose to kill seems it seems noone uses it anymore)

It is part of poppler core

Because it is not exposed there.

Sadly all you have is the code.
