Can't compile this template

[vincenzocorso]

I want to build this template using Docker.
I'm on Ubuntu 22.04 and I have Docker 22.10.17

git clone --recursive https://github.com/openmultiplayer/basic-template
cd basic-template
# I set an UID in main.cpp
cd docker
UBUNTU_VERSION=22.04 sudo ./build.sh

It pulls the ubuntu:20.04 image (but I specified the 22.04 ?)
Then during the compilation it outputs some errors:

I'm not a pro, but I think try join lib? -I path to network.
I collected and compiled everything without problems.
