I'm assuming you're talking about intermediate files when building a
custom command.  If they are listed as the OUTPUT of the custom command
they will be cleaned:

ADD_CUSTOM_COMMAND(
  OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/real_output.txt
         ${CMAKE_CURRENT_BINARY_DIR}/intermediate.txt
  COMMAND ...
  )
