I made some progress and this seems to work:

add_executable(helperapp  main.cpp)
add_executable(MyBundle MACOSX_BUNDLE main.mm )

#and copy helper into it. For now by hand.
#LOCATION seems to miss the .app fix that later..
get_target_property(MF_LOCATION MyBundle LOCATION)
get_target_property(HELPER_LOCATION helperapp LOCATION)
ADD_DEPENDENCIES(MyBundle helperapp)
add_custom_command(TARGET MyBundle
                     POST_BUILD
                     COMMAND mkdir -p ${MF_LOCATION}.app/Contents/Resources/
                     COMMAND cp ${HELPER_LOCATION}
${MF_LOCATION}.app/Contents/Resources/
                     COMMENT "add helper" VERBATIM)

still curious if this can be done better...
