# $FreeBSD$
#
# Handle dependency on *ssl ports.
#
# Feature:	SSL_DEFAULT
# Usage:	USES=ssl
# Valid ARGS:	none (build and run), build, run
#
# The user can choose which ssl library he wants with:
#
# DEFAULT_VERSIONS+=	ssl=<openssl variant>
#
# Variants being base, openssl, openssl-devel, libressl, and libressl-devel.
#
# 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
# BUILD_DEPENDS		- are added if needed
# RUN_DEPENDS		- are added if needed
