# This makefile is used to set initial DIRDEPS for top-level build
|

|
|
# targets.
|
||
|
|
#
|
||
|
|
# The basic idea is that we have a list of directories in
|
||
|
|
# DIRDEPS_TARGETS_DIRS which are relative to SRCTOP.
|
||
|
|
# When asked to make 'foo' we look for any directory named 'foo'
|
||
|
|
# under DIRDEPS_TARGETS_DIRS.
|
||
|
|
# We then search those dirs for any Makefile.depend*
|
||
|
|
# Finally we select any that match conditions like REQUESTED_MACHINE
|
||
|
|
# or TARGET_SPEC and initialize DIRDEPS accordingly.
|
||
|
