Unclear instructions about how to use plugins

[pucciland95]

Hi all, and thank you for this amazing repo :-)

I wanted to ask you why in the sleep_action.cpp file are necessary these lines. Is it not exactly the point of a plugin to NOT include the .hpp file avoiding static linking?

Should not these lines be:

#ifndef USE_SLEEP_PLUGIN
#else
#include "sleep_action.hpp"
#endif

that is including the .hpp only if you are NOT using the plugin? Am I missing something?

Cheers,
Niccolo
