[Insight-users] from image to spatial object : how to install VTK

[Luis Ibanez]

Hi Michal,


Please pay attention to the Help messages that CMake display for
you at the bottom of the GUI (MFC in Windows, Curses on Unix).


The message for the VTK_DIR variable tells you the following:



VTK_DIR:

       directory containing VTKConfig.cmake.
       This is either the root of the build tree,
       or PREFIX/lib/vtk for an installation.

       For VTK 4.0, this is the location of UseVTK.cmake.
       This is either the root of the build tree or
       PREFIX/include/vtk for an installation.


Since you are installing VTK, you must provide the directory:

    PREFIX/lib/vtk

where "PREFIX" is the directory where you installed VTK.



   Regards,



      Luis
