oh, sorry for my prev post.

i found this in qt4.jam:

# Since this generator will return H target, the linking generator
# won't use it at all, and won't set any dependency on it.

now i see next alternatives:
- implement xpidl like generators in qt4 (it's not easy)
- try this:

h vtkIVisualizationFrame
   : vtkIVisualizationFrame.idl
   ;

lib vtk-wrapper
   : plugin.cpp
   : <implicit-dependency>vtkIVisualizationFrame
     <link>shared
   ;
