You can also phrase your modules as C++-only static libraries and link 
them all together into the application. Mind that tools like Qt Creator 
or qmllint may have a hard time figuring this out and might not give you 
a meaningful analysis of your QML code. You will need to manually 
install your .qmltypes files into the import path or merge them together 
into a single one in the application directory. There is no "link" step 
for .qmltypes files (yet).

You can still manually call qmlRegisterType, but if you want qmllint and 
a future QML-to-C++ compiler to see your C++ types, you shouldn't.
