[Paraview] Plugin Basics

[Michael Jackson]

Gaaahhhhh....

I'm using a variable (SOURCES) that is actually an optional argument  
to the ADD_PARAVIEW_PLUGIN() macro.


If I change SET (SOURCES ${ParaViewExamples_SOURCE_DIR}/ 
vtkMyElevationFilter.cxx) to

SET (_SOURCES ${ParaViewExamples_SOURCE_DIR}/vtkMyElevationFilter.cxx)
ADD_PARAVIEW_PLUGIN(SMMyElevation "1.0"
  SERVER_MANAGER_XML MyElevationFilter.xml
  SERVER_MANAGER_SOURCES "${_SOURCES}"
# SERVER_MANAGER_SOURCES vtkMyElevationFilter.cxx
  )

then everything works.

Hmm. I was thinking that cmake would have done the variable  
substitution FIRST before sending it to the macro.

Is this a bug or feature?

Mike
