In my CMakeLists.txt, I have a FOREACH with a ${lib} variable.  It works
using a prefix "_" to the target name.  I believe in the UseSWIG.swig,
there is a "REAL_NAME" variable which adds an underscore for Python
only.  I don't if you are supposed to use this trick (i.e. how long will
it work), but it works with CMake 2.0.5.


  SWIG_ADD_MODULE(${lib}Python python ${SWIG_INTERFACE})

  ADD_CUSTOM_COMMAND(TARGET _${lib}Python
                        POST_BUILD
                        COMMAND ${CMAKE_COMMAND}
                        ARGS -E copy ........


In your case, your "target" is _example.
