It doesn't AFAIK.  The custom rule specified by the custom target is put
at the beginning of the post-build rules list.  Therefore the pre-build
rules do run before it.  However if there are any custom commands in the
target (using the DEPENDS argument of ADD_CUSTOM_COMMAND) I think they
will still run first.
