It looks pretty weird huh?
Well, here's what I've done explicitly in the past, and am now trying to
find some clean rules to do instead. Sure, there are other ways to do
this,
> make install-host1
building in /somedir/host1/
[etc...]
So if I have:
HOSTS := host1 host2 host3
INSTALL_HOSTS := $(addprefix install-,$(HOSTS))
# Here's my "goal"
$(INSTALL_HOSTS) : $(INSTALL_DIR) := $(subst install-,$(NULL),$@)
$(INSTALL_HOSTS) : install-all
install-all:
copy foobar /somedir/$(INSTALL_DIR)
