# Rules and Macros for building opens source software that uses configure /
# GNU auto* tools to configure their build for the system they are on.  This
# uses GNU Make to build the components to take advantage of the viewpath
# support and build multiple version (32/64 bit) from a shared source.
#
# To use these rules, include ../make-rules/configure.mk in your Makefile
# and define "build", "install" targets appropriate to building your component.
# Ex:
#
# 	build:		$(COMPONENT_SRC)/build-32/.built \
#	 		$(COMPONENT_SRC)/build-64/.built
# 
#	install:	$(COMPONENT_SRC)/build-32/.installed \
#	 		$(COMPONENT_SRC)/build-64/.installed
#
# Any additional pre/post configure, build, or install actions can be specified
# in your make file by setting them in on of the following macros:
#	COMPONENT_PRE_CONFIGURE_ACTION, COMPONENT_POST_CONFIGURE_ACTION
#	COMPONENT_PRE_BUILD_ACTION, COMPONENT_POST_BUILD_ACTION
#	COMPONENT_PRE_INSTALL_ACTION, COMPONENT_POST_INSTALL_ACTION
#
# If component specific make targets need to be used for build or install, they
# can be specified in
#	COMPONENT_BUILD_TARGETS, COMPONENT_INSTALL_TARGETS
#
