That's what I tried, but the third-party libraries are located outside my build tree, so I need to use absolute paths, which as I said does not work:

        It is impossible to order the linker search path in such a way that libraries specified as full paths will be picked by the linker.
        Directories and libraries involved are:
        Directory: c:/lang/Qt/3.3.4/lib contains:
        Library: c:\lang\qt\3.3.4r/lib/qtmain.lib

        Directory: c:/lang/qt/3.3.4r/lib contains:
        Library: C:\lang\Qt\3.3.4/lib/qtmain.lib
