# Rules and Macros for building opens source software that uses the waf
# build system from https://waf.io/
#
# To use these rules, include $(WS_MAKE_RULES)/waf.mk in your Makefile
# and define "build", "install" targets appropriate to building your component.
# Ex:
#
# 	build:		$(BUILD_32) \
#	 		$(BUILD_64)
# 
#	install:	$(INSTALL_32) \
#	 		$(INSTALL_64)
#
# Any additional pre/post configure, build, or install actions can be specified
# in your Makefile by setting them in on of the following macros:
#	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
#

# Defaults to looking for waf script in top level of cloned source
