This Makefile fragment is included by package buildlink.mk files. This

file does 3 things:

(1) Defines a macro target, _BUILDLINK_USE, that symlinks package files
    into a new hierarchy under ${BUILDLINK_DIR};
(2) Adds -I${BUILDLINK_DIR}/include to CPPFLAGS, CFLAGS, and CXXFLAGS;
(3) Adds -L${BUILDLINK_DIR}/lib to LDFLAGS.

This file might be absorbed into bsd.pkg.mk at a future date.

+# This Makefile fragment is included by package buildlink.mk files.  This
+# file does 3 things:
+#
+# (1) Defines a macro target, _BUILDLINK_USE, that symlinks package files
+#     into a new hierarchy under ${BUILDLINK_DIR};
+# (2) Adds -I${BUILDLINK_DIR}/include to CPPFLAGS, CFLAGS, and CXXFLAGS;
+# (3) Adds -L${BUILDLINK_DIR}/lib to LDFLAGS.
+#
+# By including buildlink.mk files before package-specific CFLAGS or LDFLAGS
+# are defined, you can ensure that the buildlink directories are ahead of
+# any package-specific directories in the compiler search paths.
+#
+# The variables required to be defined prior to including this file are
+# listed below.  <pkgname> refers to the name of the package and should be
+# used consistently throughout the buildlink.mk file.
+#
+# BUILDLINK_PREFIX.<pkgname>	installation prefix of the package
+#
+# BUILDLINK_FILES.<pkgname>	files relative to ${BUILDLINK_PREFIX.<pkgname>}
+#				to be symlinked into ${BUILDLINK_DIR}
+#
+# BUILDLINK_TARGETS		targets to be invoked during pre-configure;
+#				the targets should be appended to this variable
+#				using +=
+#
+# The targets required to be defined prior to including this file are
+# listed below.
+#
+# pre-configure			this target should have as dependencies any
+#				targets to be invoked; this is just usually	#				<pkgname>-buildlink
+#
+# <pkgname>-buildlink		this target should just invoke the
+#				_BUILDLINK_USE macro target defined in this
+#				file
+#
+# Example package buildlink.mk file:
+#
+# BUILDLINK_PREFIX.foo=		${LOCALBASE}
+# BUILDLINK_FILES.foo=		include/foo.h
+# BUILDLINK_FILES.foo+=		include/bar.h
+# BUILDLINK_FILES.foo+=		lib/libfoo.*
+#
+# BUILDLINK_TARGETS+=		foo-buildlink
+#
+# pre-configure: foo-buildlink
+# foo-buildlink: _BUILDLINK_USE
