The GPL and LGPL specifically say that they do not imply anything about the 
running of the application.

The licensing of the tool does not imply anything in your software, unless the 
tool copies part of its source code to the output. That is not the case for 
qmake, moc, uic, rcc, qdbusxml2cpp, qdbuscppx2xml, etc.
