#
# The problem is, that included makefiles should be aware of their relative path
# but not need to guess or hardcode it. So we set $(CURRENTPATH) for them. If
# we do this globally and the included makefiles want to include other makefiles as
# well, they would overwrite $(CURRENTPATH), screwing the include after them.
#
# By using a for-loop with an eval'd macro, we can generate the code to include all
# sub-makefiles (with the correct $(CURRENTPATH) set) before actually evaluating
# (and by this possibly changing $(CURRENTPATH)) them.
#
# This works recursively, if an included makefile wants to include, it can safely set
# $(SUBDIRS) (which has already been evaluated here) and do
# "$(foreach S,$(SUBDIRS),$(eval $(INCLUDE_FILE)))"
# $(SUBDIRS) must be relative to the project root, so to include subdir foo, set
# $(SUBDIRS) = $(CURRENTPATH)/foo.
