Installation issue with pybind11.wrap

[bakunin75]

Hey, I'm struggling with the following problem. I have to build poppler behind a proxy, i.e. I have no direct internet access.
Yet the install requires one to download pybind11 from github. Is there a way to change the pybind11 dependency somehow, use a custom source_url in the wrap file or something like this?
