Yep, John got it exactly. You'll notice that one of them is:
MyFilter/CMakeLists.txt

and the other:
MyFilter/plugin/CMakeLists.txt

The idea of this page was to demonstrate how to optionally build a subdirectory:

SET(BUILD_PARAVIEW_PLUGIN OFF CACHE BOOL "Build Paraview plugin?")

if(BUILD_PARAVIEW_PLUGIN)
 SUBDIRS(plugin)
endif(BUILD_PARAVIEW_PLUGIN)

Thanks,
