Thanks for the reply. I would do it as you said also.
My goal was to find out why _DEPENDENCIES is not doing
what I think it should. Even though this example is
contrived, the same problem happens in examples that
are not.
If a dependency of a target is not built, then Makefile
should build the dependency first. That is not what
is happening here. Why can't Makefile go to right
directory to build the dependency???

Why not have the executable outside and the library
in a subdirectory. That is how I put my libraries.
src/main.c
src/helperfunctions/helperfunctions.a
with regards,
Santosh.
