Hi, AFAIR, yes, but you are setting the dependency on the wrong level. In your top level folder, TestSuite should depend on lib like app does.

Hi and welcome to devnet, Because it's complex to integrate one build system with another. What 3rd party is it ?

Finally fixed it, i used a .qmake.conf file to store the root directory in a shared variable, for those who are interested, here are my 3 .pro files : project.pro TEMPLATE = subdirs CONFIG += ordered c++11 SUBDIRS = ircbot \ myApp myApp.depends = ircbot mylib.pro DESTDIR = $$lib_dir TARGET = mylib TEMPLATE = lib CONFIG += staticlib SOURCES += ... HEADERS += ... FORMS += ... myApp.pro DESTDIR = $$bin_dir TARGET = myApp TEMPLATE = app LIBS += $$lib_dir/libmylib.a INCLUDEPATH += ../mylib SOURCES = ... HEADERS += ... FORMS += ... and finally, the .qmake.conf file : lib_dir=$$PWD/lib bin_dir=$$PWD/bin this successfully creates this project structure : bin myApp.exe lib mylib.a project.pro .qmake.conf myApp myApp.pro mylib mylib.pro + a build directory anywhere i want

You're welcome ! Svn allows some interesting things like the use of properties that can simplify some handling for e.g. your files header.
