# This Makefile fragment is included by packages that use OpenSSL.
#
# To use this Makefile fragment, simply:
#
# (1) Optionally define USE_OPENSSL_VERSION to the mininum OpenSSL version
#     number in <openssl/opensslv.h>, i.e. 0x0090600fL, etc.
# (2) Include this Makefile fragment in the package Makefile,
# (3) Add ${BUILDLINK_DIR}/include to the front of the C preprocessor's header
#     search path, and
# (4) Add ${BUILDLINK_DIR}/lib to the front of the linker's library search
#     path.
