Compiling failed! cannot find -lserialport

[JacquesDuflos]

Hi,
working on ubunto 24.04. I try to follow step by step the indications in the readme file, but the
python3 install.py
commande dosn't work : it starts fine, it compiles lot of stuff, but it interrupts eventually with the message

Compiling godot-cpp/src/core/class_db.cpp ...

Any help ?
