Well, of the two routes (hacking evince or converting mxe to build dlls)
I feel more confident about the first and I suspect you would be better
at the second. The advantage of the first is that we would get mxe
support as the libraries change over time, the disadvantage would be we
would be on our own with any changes we might want to follow in evince.
 I guess we should push ahead with seeing which is feasible. I'll look
some more at evince - in principle I just need to replace the g*module*
stuff with stuff to point directly at the ev-poppler.cc code, bringing
that in to directly linked sources.
