# This part is included the first time make is invoked. This part defines the
# global targets and the following implicit rule which determines the
# TARGET_TYPE of the next thing to be build in the following make invocation
# (a library, application, tool etc.), the current name of the target from a
# specific library/application/tool/etc list and the OPERATION to be performed
# (all, install, clean, distclean etc.).

# This target has to be called with the name of the actual target, followed
# by the operation, then the makefile fragment to be called and then the
# variables word. Suppose for example we build the library libgmodel, the
# target should look like:
#
#	libgmodel.all.library.variables
#
%.variables:
	@(target=`echo $* | sed -e 's/\(.*\)\.\(.*\)\.\(.*\)/\1/'`; \
	operation=`echo $* | sed -e 's/\(.*\)\.\(.*\)\.\(.*\)/\2/'`; \
	type=`echo $* | sed -e 's/\(.*\)\.\(.*\)\.\(.*\)/\3/' | tr - _`; \
	$(MAKE) -f $(MAKEFILE_NAME) --no-print-directory --no-keep-going \
	    TARGET_TYPE=$${type} \
	    OPERATION=$${operation} TARGET=$${target} \
	    PROCESS_SECOND_TIME=yes $${target}.build \
	    OBJCFLAGS="$(OBJCFLAGS)" CFLAGS="$(CFLAGS)" \
