There's no such option. It all depends in the order they get added to the 
INCLUDEPATH variable in qmake, which means the order depends on the .*.pro and 
*.pri files themselves, what they include, what other libraries they try to 
pull in, etc.

Conclusion: don't. Do not build a module when that module is already installed 
in the same prefix as one of your dependencies. This applies to more than just 
Qt and is a good rule of thumb for everything.
