I have a subdirs project which wraps a couple libraries and a main application. When I change something in one of the libraries the main application does not relink with them.. does anyone have a trick for getting an application to relink with its statically linked libs automatically when using QtCreator?

    There is a workaround for this and also an interesting discussion on the subject (qmake seems to be the problem here) on the Qt Creator mailing list.

    The workaround is to add a PRE_TARGETDEPS command to your main applications .pro file, e.g.:

    PRE_TARGETDEPS += /path/to/your/lib.a

    This forces the relink.
