You have found a counter example to what I said about classes and files, and you are trying to prove me wrong by ignoring what I wrote (*common practice* and *in particular if they are complex classes*). Yet it seems we both agree that 2 complex classes (let's say QString and QObject) are often declared in different files and that a file can contain more than one class declaration, in particular if they are helper classes. Anyway, I don't see how making this point about QRegExp support your case. In fine, we are talking about qmake, not C++. I was merely illustrating my point with C++. But let's continue the comparison. You can have "helper targets" in a .pro file too. This is done by using `QMAKE_EXTRA_TARGETS` and such. However, you shouldn't have 2 full complex build targets in a single .pro file. Not only it is bad practice, but it is not supported by qmake. In the end, it is your project and you will do as you want. But you have been warned: "you are creating a trap that your future self with get stuck into" (and the QRegExp helpers won't help you then). Benjamin
