It seems that vtk is no longer required x11, it is an optional. So I think it should be added explicitely here for safety.

Thank you for the pull request. I tried to reproduce the problem by building PCL with VTK 9.6, but everything was fine. Maybe that is just because the X11 includes are in the standard include path on my computer (/usr/include). Are the includes here and here the problem, or what else is going wrong when PCL does not link to X11 explicitly?

Nothing else, that is all I think. In our CI on macos, libx11 is not include in general and so it does failed at that point. That is why I am trying to add x11 requirements here.
