make_ref.include

# This is common code for a Makefile.am and creates $(LIB_REF) to be used
# afterwards in noinst_LTLIBRARIES and EXTRA_slurmrestd_DEPENDENCIES
#
# usage
#
# REF = usage.txt
# include $(top_srcdir)/make_ref.include
# noinst_LTLIBRARIES [+]= $(LIB_REF)
# EXTRA_$PROGRAMNAME_DEPENDENCIES [+]= $(LIB_REF)
# $PROGRAMNAME_LDADD += $(LIB_REF)
#
# What the above lines do is include this file in a Makefile.am
# It will insert usage.txt as a variable that the calling program can access
# with the calls in src/common/ref.h.
#
# If I where doing this for the slurmrestd I would put 'slurmrestd' in for
# $PROGRAMNAME i.e. EXTRA_slurmrestd_DEPENDENCIES, slurmrestd_LDADD.
