Yes, environment variables are possible to use. I did not see it as an easier option
compared to just adding commandline parameter, but handling pdflatex output turned out
harder than I thought.

Surprisingly to me, going the environment way turned out to be super easy.

Can someone on windows confirm the attached patch works?
(Mac would be also nice but I am reasonably confident this works there as well.)

Just compile the introduction manual, go to the Document->LaTeX log
and check that at the very end the list of paths is superlong line.
