Has anyone managed to build the proj crate, I've tried on windows and on Ubuntu but always seem to have some problem with the proj-sys crate building proj from source.
@Kaiser If you run into trouble with something-sys, you should check whether that crate requires libsomething headers to be installed. (cargo will take care of dependencies, but only within Rust, it can't install arbitrary C libraries). On Ubuntu, you'll need to run sudo apt install libproj-dev (maybe also libtiff-dev) to get these headers.
