This project is great. I downloaded it, but it gave an error when I compiled it, saying that lwip is missing. I cloned https://github.com/lwip-tcpip/lwip, put the code into the project, but it still gave an error and could not compile successfully.

Lwip is used as a git submodule. To Initialize it properly, clear that folder again and run the command git submodule update --init --recursive
