### how to build directory structure

${BUILD_DIR}:
	mkdir ${BUILD_DIR}

${BUILD_DIR}/${LIBS_DIR}: ${BUILD_DIR}
	mkdir ${BUILD_DIR}/${LIBS_DIR}

${BUILD_DIR}/${SRC_DIR}: ${BUILD_DIR}
	mkdir ${BUILD_DIR}/${SRC_DIR}

${BUILD_DIR}/${TESTS_DIR}: ${BUILD_DIR}
	mkdir ${BUILD_DIR}/${TESTS_DIR}

${BUILD_DIR}/${LIBS_DIR}/alglib: ${BUILD_DIR}/${LIBS_DIR}
	mkdir ${BUILD_DIR}/${LIBS_DIR}/alglib

${BUILD_DIR}/${LIBS_DIR}/array_matcher: ${BUILD_DIR}/${LIBS_DIR}
