AFAICS, you need a dependency of ui_translate on the ui_*.h files:
add_custom_target(ui_translate
COMMAND ${CMAKE_SOURCE_DIR}/tools/convert-tr2-all.py
WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}
DEPENDS ${kcm_my_plugin_PART_SRCS})
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Note that this only works within the same directory, i.e.
kde4_add_ui_files() and add_custom_target() must be
mentioned in the same CMakeLists.txt.
