# 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.*
|
|
# for options.
|
|
#
|
|
# Thus a directory, that is affected by an option FOO would have
|
|
# 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
|
|
# set in local.dirdeps-options.mk
|
|
# Either way, we will .undef DIRDEPS.* when done.
|
|
#
|
|
# In some cases the value of MK_FOO might depend on TARGET_SPEC
|
|
# so we qualify MK_FOO with .${TARGET_SPEC} and each component
|
|
# TARGET_SPEC_VAR (in reverse order) before using MK_FOO.
|
|
#
|
|
|
|
# This should have been set by Makefile.depend.options
|
|
# before including us
|
