Makefile: run based on test of variable

I have a makefile with a rule to build several targets and create a single package from it.

TARGETS=t1 t2 t3 t4

pack_it:
    -for t in $(TARGETS); do \
        $(MAKE) -C $$t install DESTDIR='temp' ); \
    done
    tar czvf package.tar.gz -C tmp *

Now I'd like to be able to pass, from command line, which targets I want to pack, like this:

make pack_it t1 t4

How must I test the arguments to know if I should run make install on a target?

Thanks!

You can just override TARGETS from the command line:

$ make pack_it TARGETS="t1 t4"

No need to change anything in the makefile.
