Comment (by Roland Haas):

You would add:

LIBDIRS = /path/to/LIB_DIRS
LIBS = elliptica_id_reader

Could you provide that make output as described here http://einsteintoolkit.org/support.html#general-guidelines-for-questions

The closest equivalent is LORENE (which would be the library) and Meudon_Bin_NS (the reader).

If you have an existing code to look at and would like to take a look, that might help
