If you define a supported `-local` target (e.g. `all-local`) in `Makefile.am`, `automake` will supplement the standard target (e.g. `all`) with it.
* https://www.gnu.org/software/automake/manual/html_node/Extending.html * https://www.gnu.org/software/automake/manual/html_node/Third_002dParty-Makefiles.html But this only works, when creating separate rules for `-local` targets. When listing multiple `-local` target in one rule, they are not applied. good: all-local: echo $@ clean-local: echo $@ resulting `Makefile`: all-am: Makefile all-local clean-am: clean-generic clean-libtool clean-local mostlyclean-am bad: all-local clean-local: echo $@ resulting `Makefile`: all-am: Makefile clean-am: clean-generic clean-libtool mostlyclean-am
