    I have a subdirs project with the following structure

    main
      |__main.pro
      |__app
      |     |__app.pro
      |     |__Qxls
      |           |__qxls.pri      
      |__mylib
      |     |__mylib.pro
      |__mytest
            |__mytest.pro
    

    Everything compiles and runs fine. My issue is if I change some class in the app and compile (ctrl-b) it picks up the changes no problem. However, if I change a class in mylib or mytest ctrl-b does not pick up the changes, I have to do a rebuild which takes a few minutes and is a big waste of time. I reference Qxls from both the mylib and mytest sub projects and I suspect this is the issue, but that's just a guess. What change should I make or how do I resturcture the project to make a simple compile work for the sub projects. If you need to .pro and .pri files I can attach

      Hi and welcome to devnet,

      Static or dynamic libraries ?

        @SGaist they are static (CONFIG += staticlib) but willing to change

          In that case, you need to use PRE_TARGETDEPS.

            @agconnell can you show the main pro file, that manages your project?

              To close the loop on this, I changed the layout of the project and added PRE_TARGETDEPS as noted below. It works as expected now. Thanks!

              main
                |__main.pro
                |__app
                |     |__app.pro   
                |__mylib
                |     |__mylib.pro
                |__mytest
                |     |__mytest.pro
                |__Qxls
              		|__qxls.pro
              
              win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$OUT_PWD/../QXlsx/release/libQXlsx.a
              else:win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$OUT_PWD/../QXlsx/debug/libQXlsx.a
              else:win32:!win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$OUT_PWD/../QXlsx/release/QXlsx.lib
              else:win32:!win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$OUT_PWD/../QXlsx/debug/QXlsx.lib
              else:unix: PRE_TARGETDEPS += $$OUT_PWD/../QXlsx/libQXlsx.a
