# This makefile is used to deal with optional DIRDEPS.
|
|
|
|
|
#
|
|
|
|
|
# It is to be included by Makefile.depend.options in a
|
|
|
|
|
# directory which has DIRDEPS affected by optional features.
|
|
|
|
|
# Makefile.depend.options should set DIRDEPS_OPTIONS and
|
|
|
|
|
# may also set specific DIRDEPS.* for those options.
|
|
|
|
|
#
|
|
|
|
|
# If a Makefile.depend.options file exists, it will be included by
|
|
|
|
|
# dirdeps.mk and meta.autodep.mk
|
|

|

# We include local.dirdeps-options.mk which may also define DIRDEPS.*

|
# a Makefile.depend.options that sets
|
|
|
|
|
# DIRDEPS_OPTIONS= FOO
|
|
|
|
|
# It can also set either/both of
|
|
|
|
|
# DIRDEPS.FOO.yes
|
|
|
|
|
# DIRDEPS.FOO.no
|
|
|
|
|
# to whatever applies for that dir, or it can rely on globals
