# $NetBSD: dlopen.buildlink3.mk,v 1.18 2015/10/10 13:13:45 jperkin Exp $
#
# This Makefile fragment is included by package Makefiles and
# buildlink3.mk files for the packages that use dlopen().
#
# It defines the variables DL_CFLAGS, DL_LDFLAGS and DL_LIBS, which
# are also exported into the CONFIGURE_ENV and MAKE_ENV environments.
#
# Package-settable variables:
#
# DL_AUTO_VARS
# When set to "yes", the necessary flags are added automatically
# to CFLAGS and friends.
#
# Default: no
#
# Keywords: dl dlopen
