Qt4: Add module dependencies to the IMPORTED targets

This means for example, that consumers can use:

 target_link_libraries(foo ${QT_QTGUI_LIBRARIES})

instead of also needing to specify all 'public' dependencies:

 target_link_libraries(foo ${QT_QTGUI_LIBRARIES} ${QT_QTCORE_LIBRARIES} )

when using the IMPORTED targets.  Also populate the
IMPORTED_LINK_DEPENDENT_LIBRARIES property so CMake can help the linker
find shared library dependencies.
