The basic setup to create a Qt plugin is
- create a product of type "dynamiclibrary"
- add a JSON file and tag it with "qt_plugin_metadata"

This use case is independent from Qt plugins.
Unfortunately there's currently not a good way to call the compiler's
prepare script again. See also QBS-5.
What you can do instead is something like this
DynamicLibrary {
name: "PLUGIN1"
Depends {name: „cpp“}
Depends {name: „LIB“}
files: [...all cpp files for building the plugin...]
}
Product {
name: "PLUGIN1_LINK"
type: ["plugin_link"]
Depends {name: „PLUGIN1“}
// Rule to create the symlink for a plugin.
// Use inheritance to avoid code duplication.
}
And then let plugintester depend on the PLUGIN*_LINK products.
