+    ParaView propagates CMAKE_PREFIX_PATH to Catalyst Adaptors.
+
+    Fixes #18224
+    ParaView uses add_custom_command to build all the catalyst adaptors.
+    This means that any package find calls that occur when including
+    ParaView's Config Module need to be part of the search path for
+    the adaptor.
+
+    The easiest way is to make sure that CMAKE_PREFIX_PATH is propagated
+    through add_custom_command as it is the most common way of specifying
+    where to search.
+
+    Note: That as more projects move over to import targets this approach
+    will continue to fail especially if they specify the search directories
+    using `<Package>_ROOT`. Long term the catalyst adaptors will need to
+    become an external project or stop using add_custom_command.
