Many things changed for building plugins between paraview-5.6 and paraview-5.7, with some further (minor) refinements for paraview-5.8.

This might be one place to start:

You need to change a few things when scanning for files etc. It might be hard to follow, but here is my real-world example for building a paraview plugin both with paraview \<= 5.6 and paraview \>= 5.7. Examining the differences might give you clues for your own plugin.
