Previously, my project worked fine with vtk580. Now I want to upgrade to latest version. When I try to do I get error vtkCommon.lib not found. I have looked an not found the file in my folder.  
Can I anyone suggest solution for this?

You should consume VTK via `find_package(VTK)` and use the imported targets. These targets have changed since 5.8 quite a bit, so you’ll need some other changes. Essentially, use should look something like:

```auto
find_package(VTK COMPONENTS CommonCore)
target_link_libraries(mytgt PUBLIC VTK::CommonCore)
vtk_module_autoinit(TARGETS mytgt MODULES VTK::CommonCore) # important if you're using rendering or MPI

```

Can you please explain how to carry out these steps?
