# The makefile fragment included below provides variables that can be used
# to express dependencies on headers supplied by an in-development htslib.
# If your source file foo.c #includes <htslib/hts.h> and <htslib/kstring.h>,
# you can write the correct prerequisites for foo.o as:
#
#	HTSDIR = <path to htslib top-level directory>
#	include $(HTSDIR)/htslib.mk
#
#	foo.o: foo.c $(htslib_hts_h) $(htslib_kstring_h)

HTSPREFIX = $(HTSDIR)/
include $(HTSDIR)/htslib_vars.mk

# Rules for rebuilding an in-development htslib's static and shared libraries.
# If your program foo links with libhts, adding the appropriate prerequisite
# will cause the library to be rebuilt as necessary:
#
#	foo: foo.o $(HTSDIR)/libhts.a
#
# or similarly if your target requires any of the tools supplied:
#
#	bar.bed.bgz.tbi: bar.bed.bgz $(HTSDIR)/tabix
#		$(HTSDIR)/tabix -p bed bar.bed.bgz
