There are more ways. It should be searching multiple paths already. You can 
check web_engline_libraray_info.cpp for how it finds it. It should check 
QLibraryInfo::DataPath first and then QCoreApplication::applicationDirPath(). 
Unfortunately it seems to currently only check for the existence of the 
directory not of the data. So if the first exists then the pak files needs to 
be there.
