The AddCustomCommandToOutput is okay but there is nothing that
associates that output with the target. You should continue to use
AddUtilityCommand but with an empty command line. Instead list the
AddCustomCommandToOutput output in the "depends" list.
However, there is another problem to consider.
Look just above your patch. In VS generators we now use a PRE_BUILD
event instead of a normal custom command with an output. This was
originally motivated by issue
but makes much nicer looking VS solutions anyway. Unfortunately the
PRE_BUILD event has no "output" to clean so VS will not clean anything.
Perhaps instead we can implement ADDITIONAL_MAKE_CLEAN_FILES, at least
in VS >= 10. See the BeforeClean and AfterClean targets here:
