Is it not sufficient to create an empty target?:
task1.done: source1_a.src source1_b.src
$(EXTERNAL_UTIL_1) source1_a.src source1_b.src
touch $@
task2.done: source2_a.src source2_b.src
$(EXTERNAL_UTIL_2) source2_a.src source2_b.src
touch $@
If you need any of the files created by task 2, you just name task2.done
as the prerequisite. Or have I misunderstood?...
In the example above, any dependencies of .GROUPTARGET would be a
target-group. Each target group could be treated sort of like a conditional
PHONY that would run if any of the group's members were out-of-date.
Are you saying that $(EXTERNAL_UTIL_1) won't necessarily update all of
TASK1_OUTPUTS (otherwise, they would all be out-of-date together)?
Cheers,
Steven
