.pro to .pri

[CLTSchwarz]

I have used the ButtonQMLPlugin from the one_click_buy example for in application purchasing. I have a fully working application, however the ButtonQMLPlugin compiles into a .sis file so I am left with 2 .sis files and I can't publish that to the store.
Is there an easy way to turn ButtonQML.pro into ButtonQML.pri so that it's included in my main .sis?
If not do you have any other ideas?

If I can't do anything then I'll rewrite the IAP api into the main application, but I'd rather not spend the time doing that. Thanks.

I used the plugin in this project http://projects.developer.nokia.com/qiap
