Hi all.

I tried to create the OpenCV library with viz module using VTK 9.0.0 and 9.0.1.  
But I failed and I found that viz module needs the 8.90.0.

The ‘viz/CMakeLists.txt’ contains the following messages:

if (VTK\_VERSION VERSION\_LESS “8.90.0”)  
include({VTK\_USE\_FILE}) ocv\_target\_link\_libraries({the\_module} PRIVATE {VTK\_LIBRARIES}) else () ocv\_target\_link\_libraries({the\_module} PRIVATE {VTK\_LIBRARIES}) vtk\_module\_autoinit(TARGETS {the\_module} MODULES ${VTK\_LIBRARIES})  
endif()

if(APPLE AND BUILD\_opencv\_viz)  
ocv\_target\_link\_libraries(${the\_module} PRIVATE “-framework Cocoa”)  
endif()

if(TARGET opencv\_test\_viz)  
set\_target\_properties(opencv\_test\_viz PROPERTIES MACOSX\_BUNDLE TRUE)  
endif()

With the VTK 8.90, I think it will be successful.  
(Is it right? could someone advise me about this?)

So, where can I get the VTK 8.90?

Could you please help me…? 😢

Thank you.

VTK 8.90 is not an official release of VTK, which means that even if you use a VTK which declare this version in the CMake, there is no guarantee that everything will work (both in the VTK and OpenCV side).  
Anyway, here is a git tag I used for some projects during the 8.90 time : [e4e8a4df9cc67fd2bb3dbb3b1c50a25177cbfe68](https://gitlab.kitware.com/vtk/vtk/-/commit/e4e8a4df9cc67fd2bb3dbb3b1c50a25177cbfe68)

Looking at this CMake, it seems that OpenCV may also work with VTK 8.2. This is on older release, but if my guess is right that would be more stable.
