The problem is, what does it mean to append to a variable from the
command line?
When do you append it? To what value? In other words, given the
following makefile:
$(warning FOO = $(FOO))
FOO := bar
$(warning FOO = $(FOO))
FOO += biz
$(warning FOO = $(FOO))
all: FOO := boz
all: FOO += baz
all: ; @echo FOO = $(FOO) / '$$FOO' = $$FOO
What does make print out when you run:
make FOO+=foo
??
