# 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 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 is up to date
# WITH_OPENSSL_HACK7=yes - Use not the version in the base system on FreeBSD 7.x
#
# 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
# BUILD_DEPENDS     - are added if needed
# RUN_DEPENDS       - are added if needed
