1.11 +# The purpose of this file is to pull in non-recursive targets when performing
1.12 +# a partial tree (not top-level) build. This will allow people to continue to
1.13 +# build individual directories while some of the targets may not be normally
1.14 +# defined in that make file.
1.15 +#
1.16 +# Non-recursive targets are attached to existing make targets. The
1.17 +# NONRECURSIVE_TARGETS variable lists the make targets that modified. For
1.18 +# each target in this list, the NONRECURSIVE_TARGET_<target> variable will
1.19 +# contain a list of partial variable names. We will then look in variables
1.20 +# named NONRECURSIVE_TARGETS_<target>_<fragment>_* for information describing
1.21 +# how to evaluate non-recursive make targets.
1.22 +#
1.23 +# Targets are defined by the following variables:
1.24 +#
1.25 +# FILE - The make file to evaluate. This is equivalent to
1.26 +# |make -f <FILE>|
1.27 +# DIRECTORY - The directory whose Makefile to evaluate. This is
1.28 +# equivalent to |make -C <DIRECTORY>|.
1.29 +# TARGETS - Targets to evaluate in that make file.
1.30 +#
1.31 +# Only 1 of FILE or DIRECTORY may be defined.
1.32 +#
1.33 +# For example:
1.34 +#
1.35 +# NONRECURSIVE_TARGETS = export libs
1.36 +# NONRECURSIVE_TARGETS_export = headers
1.37 +# NONRECURSIVE_TARGETS_export_headers_FILE = /path/to/exports.mk
1.38 +# NONRECURSIVE_TARGETS_export_headers_TARGETS = $(DIST)/include/foo.h $(DIST)/include/bar.h
1.39 +# NONRECURSIVE_TARGETS_libs = cppsrcs
1.40 +# NONRECURSIVE_TARGETS_libs_cppsrcs_DIRECTORY = $(DEPTH)/foo
1.41 +# NONRECURSIVE_TARGETS_libs_cppsrcs_TARGETS = /path/to/foo.o /path/to/bar.o
1.42 +#
1.43 +# Will get turned into the following:
1.44 +#
1.45 +# exports::
1.46 +# $(MAKE) -C $(DEPTH) -f /path/to/exports.mk $(DIST)/include/foo.h $(DIST)/include/bar.h
1.47 +#
1.48 +# libs::
1.49 +# $(MAKE) -C $(DEPTH)/foo /path/to/foo.o /path/to/bar.o
