#
# 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
