[vtk-developers] Hi, can I compile a code using CUDA C and VTK?

[Robert Maynard]

Here is an example CMakeLists.txt that combines VTK file reading and cuda.

project(Example)

#you should only need a couple vtk libraries
find_package(VTK 6.0
  COMPONENTS
  vtkCommonCore
  vtkCommonDataModel
  vtkCommonExecutionModel
  vtkIOLegacy
  REQUIRED)

find_package(CUDA REQUIRED)

#since we don't have any vtk factories this will work.
include(${VTK_USE_FILE})

#list your cuda and c++ source files
set(sources
  main.cpp
  cuda_example.cu
  )

cuda_add_executable(example ${sources})
target_link_libraries(example
  vtkCommonCore
  vtkCommonDataModel
  vtkCommonExecutionModel
  vtkIOLegacy)
