Installing Arduino plugin on QT 5.12.5

[K-Str]

Hi,
I'm using QT since some years and I'm almost satisfied. Even with the help I got here.
The next projectsd are to programm Arduinos and my question is how to install a plugin to make this.
I cannot find an actual tutorial which describes this completely. I found only fregments how to do it. With most of them there ar some parts missing and there is no information how to solve this.

@K-Str What plug-in do you mean?

@jsulm ,
thanks a lot for your answer.
I followed this instructions:
installing arduino and atmel templates
But now I have problems to configure Qt-Creator to compile the program.
First of all it doesn't find libraries like Serial .
How do to install this?
On the Arduino IDE I can add this libraries using the add library feature.

You can do the same in QtCreator - right click on your project and then "Add Library..."
