Hi all,

I have libvtk9-dev installed on Ubuntu 22.04 Jammy, and using it within my project to write my output to vtp file, I importing it to my project through CMake.  
`find_package(VTK REQUIRED)`  
`target_link_libraries(sim PRIVATE ${VTK_LIBRARIES} OpenSSL::Crypto)`

But I want to visualize my results, i tried to install paraview through `sudo apt get paraview`, but it seems there is a conflict between paraview and vtk9 and it removes libvtk9-dev during installation as seen in the attachment. Then my program crashes and cannot build because it can not find vtk anymore. Is there a way to install paraview without removing libvtk9-dev?

Thank you in advance.

Hi @Hisham

It is a known issue of the debian packages, there is an issue on ParaView gitlab to find a solution but nothing came up so far:

Hi @mwestphal

Thank you for your help. I used libvtk7-dev instead.  
during running the `find_package` by the cmake file I get some missing reference, but it still builds. so for me this solves the problem for now.
