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.
