[Paraview] paraview plugins and python

[Pat Marion]

This will do it:

# CMakeLists.txt

include(wrap-python.cmake)

add_paraview_plugin(${library_name} ...)
target_link_libraries(${library_name} ${deps})

if(VTK_WRAP_PYTHON)
  wrap_python(${library_name} "${sources}")
endif()




# wrap-python.cmake
if(NOT DEFINED VTK_CMAKE_DIR)
  message(SEND_ERROR "VTK_CMAKE_DIR is not defined, cannot load
vtkWrapPython.cmake")
endif()

if(NOT VTK_WRAP_PYTHON)
  message(FATAL_ERROR "VTK was built without Python enabled
(VTK_WRAP_PYTHON=FALSE).")
endif()

include(${VTK_CMAKE_DIR}/vtkWrapPython.cmake)
function(wrap_python library_name sources)
  vtk_wrap_python3(${library_name}Python generated_python_sources
"${sources}")
  add_library(${library_name}PythonD ${generated_python_sources})
  add_library(${library_name}Python MODULE ${library_name}PythonInit.cxx)
  target_link_libraries(${library_name}PythonD ${library_name})
  foreach(c ${VTK_LIBRARIES})
    target_link_libraries(${library_name}PythonD ${c}PythonD)
  endforeach(c)
  target_link_libraries(${library_name}Python ${library_name}PythonD)
  set_target_properties(${library_name}Python PROPERTIES PREFIX "")
  if(WIN32 AND NOT CYGWIN)
    set_target_properties(${library_name}Python PROPERTIES SUFFIX ".pyd")
  endif(WIN32 AND NOT CYGWIN)
endfunction()
