# 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
