Well, you haven't used any target-specific variable settings here so... ??
This makefile is confused. You cannot have a line like this:
j> ifneq ($(strip $(foreach f,$(P),$(findstring $(f),$@))),)
and have it make any sense. The value $@ is an automatic variable: it
has a value ONLY in the context of running a particular rule, but here
you're using it in a preprocessor statement (ifneq), which is expanded
as the makefile is read in... at that time $@ has no value and so it's
replaced with the empty string. Thus, your test will never be true as
it's looking for $(f) in a constant empty string.
Not to mention you don't want to use findstring here, since this:
$(findstring foo.o,barfoo.o)
will return true (or, really, "foo.o") when you expect it to return
false (empty). You should be using filter and/or filter-out here, as
those test entire words not just substrings.
Why don't you just say:
P = pp qq
T = pp rr
CFLAGS = -c
.PHONY: $(T)
all: $(T)
$(P): CFLAGS += -g
$(T):
@echo $@ $(CFLAGS)
That gives a rule for all targets in variable T, and it sets all targets
in variable P to have a target-specific variable "CFLAGS += -g", which
is I think what you wanted.
