[vtkusers] VTK_USE_RENDERING required in CMake during example configuration, but no such option was available when configuring VTK

[Eriksson, Mikael]

Hi all,

I am a newbie to ITK and VTK. I have built both ITK and VTK and they seem to run just fine (e.g. the QuickViewDemo example worked perfectly, http://www.vtk.org/Wiki/ITK/Examples/QuickViewDemo). However, I run into trouble when I try to build other examples, such as the DistancePointToLine, http://www.vtk.org/Wiki/VTK/Examples/Cxx/SimpleOperations/DistancePointToLine. When configuring in CMake (I use Windows 7 Enterprise, 64-bit version btw) I get the following error.

CMake Error at CMakeLists.txt:6 (MESSAGE):
Example SimpleOperations requires VTK_USE_RENDERING.

The CMakeLists.txt-file, as seen on the example Wiki-page, is:

cmake_minimum_required(VERSION 2.8)
PROJECT(DistancePointToLine)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
add_executable(DistancePointToLine MACOSX_BUNDLE DistancePointToLine)
if(VTK_LIBRARIES)
  target_link_libraries(DistancePointToLine ${VTK_LIBRARIES})
else()
  target_link_libraries(DistancePointToLine vtkHybrid)
endif()

If I understand things correctly, VTK_USE_RENDERING has been an option in CMake under the VTK-group in previous versions of VTK? However, when I configure VTK with CMake I don't get this option, even though I tick the Advanced-checkbox. Under the Modules-group there are some Modules called something containing rendering which I could tick, but most seem to be for rendering with e.g. Python, Tcl etc. so I doubt that I need to add them to the configuration.

Can anybody suggest how to proceed? I suspect I need to rebuild VTK and do something differently to get the rendering to work, but without the explicit option VTK_USE_RENDERING I'm stuck.

Best regards,
Mikael
