I have learned that I can not bundle audio/video files within resource file in order to play them in my qml.
So, I have tried to use DEPLOYMENTFOLDERS in .pro file it does not copy the files. It seems that QtCreator does not generate necessary code contents using DEPLOYMENTFOLDERS in .pri file.
Is there an easy way to say copy these files into build output location? Visual studio C# has this option just saying one true/false to do this. It should not be this hard. :-)
