5# MakeInc.dir contains the recursion rules for the build system.
6# For instance, the "build_installhdrs_md" target is auto-generated
7# such that make(1) recurses into a specified set of subdirectories
8# (building "build_installhdrs_md" in turn at each level) before
9# building the special "do_installhdrs_md" target at the current
10# level. "do_installhdrs_md" is defined in MakeInc.rule.
11#
12
13# $(1) is the name of the target to produce that will perform the
14#      recursive behavior via dependencies
15# $(2) is a list of subdirectories to recurse into
16# $(3) is the target to build with a sub-make after
17#      the subdirectories have been recursed into
18# $(4) should be "1" if TARGET should be pinned to the per-arch
19#      build COMPONENT directory, or empty if it should recurse
20#      in lockstep with the source recursion
