#
# This is a makefile.am fragment to build Orc code.
#
# Define ORC_SOURCE and then include this file, such as:
#
# ORC_SOURCE=gstadderorc
# include $(top_srcdir)/common/orc.mak
#
# This fragment will create tmp-orc.c and gstadderorc.h from
# gstadderorc.orc.
#
# When 'make dist' is run at the top level, or 'make orc-update'
# in a directory including this fragment, the generated source
# files will be copied to $(ORC_SOURCE)-dist.[ch]. These files
# should be checked in to git, since they are used if Orc is
# disabled.
#
# Note that this file defines BUILT_SOURCES, so any later usage
# of BUILT_SOURCES in the Makefile.am that includes this file
# must use '+='.
