[Interest] Automatic relink of executable after change in dependant static library

[Enmaniac Software]

Thanks Joerg,

Personally, I do have some experience with Cmake but my project is quite simple and I thought Qmake should be able to handle it saving me from one external dependency. If in the future it gets more complex, thanks to you all, I have a nice list of tools to choose from!

Cheers!

Exactly. For cross-platform projects this is a big pain point of qmake.

You've already got recommendations for "bigger hammers", but I recommend to have a look at qbs where this particular case of dependency tracking works out of the box.
