#
# Most of the buildlink3.mk file is protected against multiple inclusion,
# except for the parts related to manipulating BUILDLINK_DEPTH and adding
# to BUILDLINK_DEPENDS.
#
# Note that if a buildlink3.mk file is included, then the package Makefile
# has the expectation that it can use the value of BUILDLINK_PREFIX.<pkg>.
# If the buildlink3.mk tries to handle dependencies satisfied directly by
# the base system, then it should provide an appropriate value for
# BUILDLINK_PREFIX.<pkg> for that case.  The case where a dependency is
# satisfied by a pkgsrc-installed package is handled automatically by this
# file.
#
# The different variables that may be set in a buildlink3.mk file are
# described below.
#
# The variable name convention used in this Makefile are:
#
# BUILDLINK_*	public buildlink-related variables usable in other Makefiles
# _BLNK_*	private buildlink-related variables to this Makefile
