[vtkusers] volume mapper error

[Franks]

I am using VTK8.1.1 on arch linux. I don't know much about your problem since
I am the beginner of the VTK. I hope my following suggestion would be
beneficial for you.

1. Do you link all required libraries? "vtkSmartVolumeMapper" will call
"vtkOpenGLGPUVolumeRayCastMapper ". Here is my CmakeLists.txt

  cmake_minimum_required(VERSION 3.12)
  project(test)

  set(CMAKE_CXX_STANDARD 11)

  #vtk
  # the root to find Config
  set(VTK_ROOT /opt/VTK/DEBUG)
  find_package(VTK REQUIRED)
  include(${VTK_USE_FILE})

  add_executable(${PROJECT_NAME} main.cpp)
  target_link_libraries(${PROJECT_NAME} ${VTK_LIBRARIES})

2. this link may help you.
