# - 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
