Declare additional classpath in pom.xml when using Maven ?

[ghost]

I know this is not exactly related to QtJambi, but I can't seem to define additional runtime Class Paths in my pom.xml file.
I am using Java + Maven + Intellij IDEA

The Test app works if I do the steps in https://github.com/larina3315/QtJambi-with-IDE/blob/main/README.md and use the Project Structure menu, but I cannot seem to declare the Qt library directory as an addition Java Library/Class path mentioned in https://github.com/OmixVisualization/qtjambi#execute-example (the -Djava.library.path=/Qt/6.5.3/gcc_64/lib part)

I would be grateful if someone could tell me/knows how to declare the Qt library in Maven pom.xml. ( this is my pom.xml https://pastebin.com/NcXhvEn6 )

I don't know how to specify library path in pom file. Maybe you find answers in a Maven forum.
