# Use of 'USE_OPENSSL=yes' includes this Makefile after bsd.ports.pre.mk
#
# the user/port can now set this options in the makefiles.
#
# WITH_OPENSSL_BASE=yes	- Use the version in the base system.
# WITH_OPENSSL_PORT=yes	- Use the port, even if base if up to date
# WITH_OPENSSL_BETA=yes	- Use a snapshot of recent openssl
#
# USE_OPENSSL_RPATH=yes	- pass RFLAGS options in CFLAGS,
#			  needed for ports who don't use LDFLAGS
#
# Overrideable defaults:
#
# OPENSSL_SHLIBVER=	3
# OPENSSL_PORT=		security/openssl
#
# The makefile sets this 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
# LIB_DEPENDS		- are added if needed
