# $FreeBSD$
# bsd.openssl.mk - Support for OpenSSL based ports.
#
# Use of 'USE_OPENSSL=yes' includes this Makefile after bsd.ports.pre.mk
#
# The user/port can now set these options in the Makefiles.
#
# WITH_OPENSSL_BASE=yes	- Use the version in the base system.
# WITH_OPENSSL_PORT=yes	- Use the OpenSSL port, even if base is up to date.
#
# USE_OPENSSL_RPATH=yes	- Pass RFLAGS options in CFLAGS,
#			  needed for ports who don't use LDFLAGS.
#
# Overrideable defaults:
#
# OPENSSL_SHLIBVER=	8
# OPENSSL_PORT=		security/openssl
#
# The Makefile sets these variables:
# OPENSSLBASE		- "/usr" or ${LOCALBASE}
# OPENSSLDIR		- path to openssl
# OPENSSLLIB		- path to the libs
# OPENSSLINC		- path to the matching includes
# OPENSSLRPATH		- rpath for dynamic linker
#
# MAKE_ENV		- extended with the variables above
# CONFIGURE_ENV		- extended with LDFLAGS
# BUILD_DEPENDS		- are added if needed
# RUN_DEPENDS		- are added if needed
