In other word. Stephane is trying to link an executable to a static
lib (libvtkgdcm.a) which also links to vtk (libvtkRendering.a), and
this executable requires the use of symbols from libvtkWidgets.a. when
doing the link on mingw, this gives an error message about duplicate
symbols. Since I am not at expert at both (mingw / static) I suggested
to post the question here.
