Handle "VTK::" prefix instead of "vtk" used by previous VTK versions for targets. Corrected unexpected location of endif() and broken indentation. Obsolete $VTK_USE_FILE is no more included (basing on VTK version check). Standard_WarningsDisable.hxx/Standard_WarningsRestore.hxx pair is now used to suppress VTK warnings instead of partial disabling.
