Hi,

Building plugin was OK with paraview-5.4.x. Moved to 5.8.0 and hit this :  
Unknown CMake command “ADD\_PARAVIEW\_PLUGIN”.

In 5.4, INCLUDE(${PARAVIEW\_USE\_FILE}) was needed in CMakeLists.txt. In 5.8 cmake says “remove that line, no more needed” : when removed ADD\_PARAVIEW\_PLUGIN is not found ?!.. Any clue ?

Note : FIND\_PACKAGE is called in a “master” CMakeLists.txt, ADD\_PARAVIEW\_PLUGIN is called in a “slave” CMakeLists.txt (included by “master” using ADD\_SUBDIRECTORY)

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:  
[https://discourse.paraview.org/t/building-plugins-modules-with-paraview-5-7-0-cmake/](https://discourse.paraview.org/t/building-plugins-modules-with-paraview-5-7-0-cmake/)

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.

Waow… Doc does not help much, and, fuzzy examples blur the backbone logic (personal opinion).  
Is there a “1, 2, 3 steps” check list to describe how to migrate a plugin from older version to 5.8 ?..

Here is the doc : [https://kitware.github.io/paraview-docs/nightly/cxx/PluginMigration.html](https://kitware.github.io/paraview-docs/nightly/cxx/PluginMigration.html)

As always, take a look into Examples/Plugins in ParaView source code.
