Building and installing the mavlink router on a nano pi neo

Hello, I’m a newbie. In my studies, I was given the task to install the MAVLINK ROUTER on a NANO PI NEO single-board computer. At the moment, I have connected to the internet with this computer via an Internet modem. There is a repository with the mavlink_c_library_v2 library. Help me navigate this problem. Opened a website but with the command line almost did not work . It’s just that the deadlines are tight and there are a lot of other tasks.
