FATAL Error: poll.h: No such file or directory

[RensA22]

When adding this library to my project like described in the Readme.md, i get the following error.

In file included from /home/bumblebee/dev/optimal-sensor/lib/Modbus/src/Serial/connection.cpp:5:
/home/bumblebee/dev/optimal-sensor/lib/Modbus/include/MB/Serial/connection.hpp:15:10: fatal error: poll.h: No such file or directory
15 | #include <poll.h>

Weird, this should be part of Linux development headers.

Do you have this file on your system: /usr/include/poll.h ?
