If your targets are related by some part of their filename (and,
ideally, also related to the file they're built from that way) then you
can use a pattern rule. Pattern rules with multiple targets have the
quality you're looking for:
%.c %.h : %.in
etc.

Something like this is the only way to do it if the targets have no
relationship that can be expressed as a pattern. Generally the best way
is something like:
target1 target2: falsetarget ;
falsetarget: dep
command to generate all targets
@touch $@
