#
# Rules and Macros for building open source software that uses the CMake utility
# from Kitware (http://www.cmake.org) to configure the build. 
# This file implements the same rules as configure.mk and thus uses GNU Make
# to build the components with support of multiple version (32/64 bit).
#
# To use these rules, include ../make-rules/cmake.mk in your Makefile
# and define "build", "install", and "test" targets appropriate to building
# your component.
# Ex:
#
# 	build:		$(SOURCE_DIR)/build/$(MACH32)/.built \
#	 		$(SOURCE_DIR)/build/$(MACH64)/.built
#
#	install:	$(SOURCE_DIR)/build/$(MACH32)/.installed \
#	 		$(SOURCE_DIR)/build/$(MACH64)/.installed
#
#	test:		$(SOURCE_DIR)/build/$(MACH32)/.tested \
#	 		$(SOURCE_DIR)/build/$(MACH64)/.tested
#
# 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_CMAKE_ACTION, COMPONENT_POST_CMAKE_ACTION
#	COMPONENT_PRE_BUILD_ACTION, COMPONENT_POST_BUILD_ACTION
#	COMPONENT_PRE_INSTALL_ACTION, COMPONENT_POST_INSTALL_ACTION
#	COMPONENT_PRE_TEST_ACTION, COMPONENT_POST_TEST_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
#	COMPONENT_TEST_TARGETS
#

CMAKE_PREFIX =	/usr

#
# Define path the same way as configure.mk
# Ref: http://www.cmake.org/cmake/help/v2.8.12/cmake.html#module:GNUInstallDirs
