19 # This makefile is used to deal with optional DIRDEPS.
21 # It is to be included by Makefile.depend.options in a
22 # directory which has DIRDEPS affected by optional features.
23 # Makefile.depend.options should set DIRDEPS_OPTIONS and
24 # may also set specific DIRDEPS.* for those options.
26 # If a Makefile.depend.options file exists, it will be included by
27 # dirdeps.mk and meta.autodep.mk
29 # We include local.dirdeps-options.mk which may also define DIRDEPS.*
32 # Thus a directory, that is affected by an option FOO would have
33 # a Makefile.depend.options that sets
34 # DIRDEPS_OPTIONS= FOO
35 # It can also set either/both of
38 # to whatever applies for that dir, or it can rely on globals
39 # set in local.dirdeps-options.mk
40 # Either way, we will .undef DIRDEPS.* when done.
42 # In some cases the value of MK_FOO might depend on TARGET_SPEC
43 # so we qualify MK_FOO with .${TARGET_SPEC} and each component
44 # TARGET_SPEC_VAR (in reverse order) before using MK_FOO.
47 # This should have been set by Makefile.depend.options
51 # pickup any DIRDEPS.* we need
52 .-include <local.dirdeps-options.mk>
