Yep.  But then, if foo-true and/or foo-false have dependencies in
common with other targets, parallel builds may lose.

Maybe you can have something like:

foo:
@if test; then \
  $(MAKE) foo-true; \
else \
  $(MAKE) foo-false; \
fi

I'm pretty sure this is portable - but feel free to correct me if I'm wrong.
Not sure how much of this will get past automake though; that may depend on
which targets you want to conditionalize.

Basically, you can't.  This just can't be done with portable Makefile
rules, in general.

Conditonnal

[Florent. Devin]

Hi,
How can I make a Makefile based on automake to be conditionnal
at make time and not at configure time.
I have to do this in my Makefile :
ifeq "$(shell if [ -f $(DEPEND) ]; then echo EXISTS; fi)" ""
all: $(PROG)
include $(DEPEND)
else
all: depend
endif

So it requires make time checking because it generates differents
files depending on what it has been generated before.

Please Help.
