Refael from SOOMLA here
Are you using the SOOMLA dashboard or the opensource project cocos2dx-store ?
If you’re using the dashboard you can use our premium support through email@example.com.
If you’re using the cocos2dx-store you can open an issue in Github http://github.com/soomla/cocos2dx-store/issues
As for your question: you need to add the libraries in the XCode project.
