Currently working on bookwyrm's downloading component. I began by using cpr, a spiritual port of Python's requests to C++, but it lacks some features I will require in the future. So now I'm learning to do the same things with libcurl.

EDIT: so far I've submoduled all dependencies in a lib/ directory. Should I do this with curl also, or is it safe to presume it (and its headers) are already installed on the users system? Or should I ask users to install that before building?
