9.0.0.rc1 ContextOpenGL2 not built

Hi Elvis, I am new to VTK - please could you help - where exactly do you add this line in the CMake file? I am currently just trying to run the Glyph3DImage example, but when I run CMake I get this error: “Skipping Glyph3DImage: Could not find the VTK package with the following required components: RenderingContextOpenGL2.” The CMake file currently looks like this:

cmake_minimum_required(VERSION 3.3 FATAL_ERROR)

project(Glyph3DImage)

find_package(VTK COMPONENTS 
  vtkCommonColor
  vtkCommonCore
  vtkCommonDataModel
  vtkFiltersSources
  vtkIOImage
  vtkInteractionStyle
  vtkRenderingContextOpenGL2
  vtkRenderingCore
  vtkRenderingFreeType
  vtkRenderingGL2PSOpenGL2
  vtkRenderingOpenGL2 QUIET) 
if (NOT VTK_FOUND)
  message("Skipping Glyph3DImage: ${VTK_NOT_FOUND_MESSAGE}")
  return ()
endif()
message (STATUS "VTK_VERSION: ${VTK_VERSION}")
if (VTK_VERSION VERSION_LESS "8.90.0")
  # old system
  include(${VTK_USE_FILE})
  add_executable(Glyph3DImage MACOSX_BUNDLE Glyph3DImage.cxx )
  target_link_libraries(Glyph3DImage PRIVATE ${VTK_LIBRARIES})
else ()
  # include all components
  add_executable(Glyph3DImage MACOSX_BUNDLE Glyph3DImage.cxx )
  target_link_libraries(Glyph3DImage PRIVATE ${VTK_LIBRARIES})
  # vtk_module_autoinit is needed
  vtk_module_autoinit(
    TARGETS Glyph3DImage
    MODULES ${VTK_LIBRARIES}
    )
endif () 

Many thanks
