• # - Try to find mbedTLS
  # Once done this will define
  #
  # Read-Only variables
  #  MBEDTLS_FOUND - system has mbedTLS
  #  MBEDTLS_INCLUDE_DIR - the mbedTLS include directory
  #  MBEDTLS_LIBRARY_DIR - the mbedTLS library directory
  #  MBEDTLS_LIBRARIES - Link these to use mbedTLS
  #  MBEDTLS_LIBRARY - path to mbedTLS library
  #  MBEDX509_LIBRARY - path to mbedTLS X.509 library
  #  MBEDCRYPTO_LIBRARY - path to mbedTLS Crypto library
  #
  # Hint
  #  MBEDTLS_ROOT_DIR can be pointed to a local mbedTLS installation.
