Oops. Obviously I should have has a 


  set_property(TARGET ${_target} 
    APPEND PROPERTY 
      INCLUDE_DIRECTORIES ${additional_INCLUDE_DIRECTORIES}
  )

or 

  set_property(TARGET ${_target} 
    PROPERTY 
      INCLUDE_DIRECTORIES ${additional_INCLUDE_DIRECTORIES}
  )

somewhere in the list of commands there.

Thanks,

Steve.
