I suggest to reconsider the information which is provided in the section “Handling Tools that Produce Many Outputs”. Will the relevance of the other referenced approaches evolve? * Rule item delimiter “&:” https://www.gnu.org/software/make/manual/html_node/Multiple-Targets.html#Rules-with-Grouped-Targets * Operator “+” for specifying target groups https://docs.oracle.com/cd/E88353_01/html/E37839/make-1s.html#REFMAN1make-1s-usag Regards, Markus
