# FindOpenSSL
# -----------
#
# Find the OpenSSL encryption library.
#
# Imported Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` targets:
#
# ``OpenSSL::SSL``
# The OpenSSL ``ssl`` library, if found.
# ``OpenSSL::Crypto``
# The OpenSSL ``crypto`` library, if found.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``OPENSSL_FOUND``
# System has the OpenSSL library.
# ``OPENSSL_INCLUDE_DIR``
# The OpenSSL include directory.
# ``OPENSSL_CRYPTO_LIBRARY``
# The OpenSSL crypto library.
# ``OPENSSL_SSL_LIBRARY``
# The OpenSSL SSL library.
# ``OPENSSL_LIBRARIES``
# All OpenSSL libraries.
# ``OPENSSL_VERSION``
# This is set to ``$major.$minor.$revision$patch`` (e.g. ``0.9.8s``).
