# - Try to find the OpenSSL encryption library
# Once done this will define
#
# OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL
#
# Read-Only variables:
# OPENSSL_FOUND - system has the OpenSSL library
# OPENSSL_INCLUDE_DIR - the OpenSSL include directory
# OPENSSL_LIBRARIES - The libraries needed to use OpenSSL
