[Paraview] How can I fix the problem?

[David E DeMarle]

Yes it shouldn't be necessary to move your code in with the paraview code.

I think each of your calls to ADD_PARAVIEW_PLUGIN is probably
overriting the previous ones. Simply call the macro once like so:

FIND_PACKAGE(ParaView REQUIRED)
INCLUDE(${PARAVIEW_USE_FILE})

ADD_PARAVIEW_PLUGIN(
   myReader "1.0"
  SERVER_MANAGER_SOURCES vtkMyReader.cxx
  SERVER_MANAGER_XML reader.xml
  GUI_RESOURCE_FILES pqReader.xml)
