build - Support concurrent SUBDIR traversal, fix make depend bug
[dragonfly.git] / share / mk / bsd.subdir.mk
1 # The include file <bsd.subdir.mk> contains the default targets
2 # for building subdirectories. 
3 #
4 # For all of the directories listed in the variable SUBDIRS, the
5 # specified directory will be visited and the target made. There is
6 # also a default target which allows the command "make subdir" where
7 # subdir is any directory listed in the variable SUBDIRS.

10 # +++ variables +++
11 #
12 # SUBDIR        A list of subdirectories that should be built as well.
13 #               Each of the targets will execute the same target in the
14 #               subdirectories.
15 #
16 # SUBDIR_ORDERED A list of subdirectories which also must be included in
17 #               in SUBDIR which have ordering requirements.  If this
18 #               Make variable does not exist then all subdirectories are
19 #               assumed to be strictly ordered.
