VTK_USE_FILE

Development
9

Before VTK 9, I was still able to compile this rather old lib found in the VTK journal.

My knowledge of C++ and CMake being more or less void, is there an easy fix to this CMakeList to make it VTK 9-compilable?

project( vtkMeshGeodesics )

find_package( VTK REQUIRED )
include( ${VTK_USE_FILE} )

set( vtkMeshGeodesics_SRCS
  vtkPolyDataGeodesicDistance.cxx
  vtkFastMarchingGeodesicDistance.cxx
  vtkFastMarchingGeodesicPath.cxx
  vtkPolygonalSurfaceContourLineInterpolator2.cxx )
set( vtkMeshGeodesics_HDRS
  vtkPolyDataGeodesicDistance.h
  vtkFastMarchingGeodesicDistance.h
  vtkFastMarchingGeodesicPath.h
  vtkPolygonalSurfaceContourLineInterpolator2.h )

include_directories( 
  ${CMAKE_CURRENT_SOURCE_DIR}/../FastMarching 
  ${CMAKE_CURRENT_SOURCE_DIR}/../FastMarching/gw_core
  ${CMAKE_CURRENT_SOURCE_DIR}/../FastMarching/gw_geodesic
)

add_library( vtkMeshGeodesics
  ${vtkMeshGeodesics_SRCS}
  ${vtkMeshGeodesics_HDRS} )
target_link_libraries( vtkMeshGeodesics MeshGeodesics )

Removing the VTK_USE_FILE line removes the CMake warning but compilation terminates with: fatal error: vtkPolyDataAlgorithm.h: file not found

I tried appending

vtk_module_autoinit(
  TARGETS vtkMeshGeodesics
  MODULES
    VTK::WrappingTools
    [...]
)

“[…]” being replaced by the list of all VTK modules I could find with a very subtle: grep "Create imported target VTK::" VTK-9.0.1/build/lib/cmake/vtk-9.0/VTK-targets.cmake | cut -c25- but it did not help.

So… is this easily fixable?
