I just upgraded from VTK-8.1.2 to VTK-9.0.0 and am getting a new segmentation fault:
[2A4FCA]vtkRayCastImageDisplayH:20
WARN| Error: no override found for ‘vtkRayCastImageDisplayHelper’.
Segmentation fault: 11
The offending line in my code is
m\_smartVolumeMapperSurfaceRendered = vtkSmartPointer::New();
where the smart pointer has been declared in the corresponding .h file
vtkSmartPointer m\_smartVolumeMapperSurfaceRendered;
I’m wondering if it is because, to get CMake to Configure and Generate, I had to remove the depreciated line in my CMake file
include(${VTK\_USE\_FILE})
but have not replaced it with anything.
Otherwise, it seems strange that I suddenly can’t declare a vtkSmartVolumeMapper object after upgrading VTK.
Any help would be appreciated.

You’ll need to use the `autoinit` macros to do the work that `find_package` used to do behind the scenes.
```auto
target_link_libraries(mytarget ${any_vis} VTK::ModuleName1 VTK::ModuleName2)
# Add the following line.
vtk_module_autoinit(TARGETS mytarget MODULES VTK::ModuleName1 VTK::ModuleName2)
```

That worked!! Here are the two key lines in my CMake file for my project “bonezone”
target\_link\_libraries(bonezone ${Glue} ${VTK\_LIBRARIES} ${ITK\_LIBRARIES} ${OpenCV\_LIBS})
vtk\_module\_autoinit(TARGETS bonezone MODULES ${VTK\_LIBRARIES} )
Many thanks.

How about include dirs? ${VTK\_INCLUDE\_DIRS} is empty and the generated project has no reference to VTK dirs at all when I check in visual studio ☹ ???

Use the targets. They get you everything you need.

Thanks, solved it! I also had to put it after linked\_targets call in cmake 😕 that solved it for me!

Before VTK 9, I was still able to compile [this rather old lib found in the VTK journal](https://www.vtkjournal.org/browse/publication/891).
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?

try using `include_directories(${VTK_INCLUDE_DIRS})` instead of
`include( ${VTK_USE_FILE} )` 🙂

I also had to add `target_link_libraries( vtkMeshGeodesics MeshGeodesics ${VTK_LIBRARIES} )` for all the includes to be found! Now it doesn’t compile, but for other reasons. Thanks @Mathilde!
