[vtkusers] Re: Problem moving from win to linux

[Matteo Campana]

Hi Peter
Thank you for your reply.

In CMakeList I wrote  LINK_LIBRARIES(vtkHybrid vtkGraphics).......everything
works now!

I just find it strange....I use static libraries also in Windows and i don't
need to write any LINK_LIBRARIES command in CMakeList...(I use VisualStudio
6.0 )
I only used the TARGET_LINK_LIBRARIES command
The CMakeList file looks like:
.
.
TARGET_LINK_LIBRARIES( EmbryomicsTool
 AuxiliaryLibrary VIPframeworkLibrary ModulesLibrary ComponentsLibrary
 ITKAlgorithms ITKBasicFilters ITKCommon ITKIO ITKNumerics
 vtkRendering vtkGraphics vtkHybrid vtkImaging vtkIO vtkFiltering vtkCommon
vtkParallel
 ${FLTK_LIBRARIES})
.
.
In Linux I also have to explicitly link the 2 libraries by LINK_LIBRARIES.
Anyway...Thank You  so much!!
Matteo
