# Try to find the Mbed TLS libraries.

# Sets the following:
#
# MBEDTLS_INCLUDE_DIR - Where to find mbedtls/ssl.h, etc.
# MBEDTLS_FOUND - True if we found Mbed TLS.
# MBEDTLS_CRYPTO_LIBRARY - The mbedcrypto library.
# MBEDTLS_X509_LIBRARY - The mbedx509 library.
# MBEDTLS_TLS_LIBRARY - The mbedtls library.
# MBEDTLS_LIBRARIES - List of all three Mbed TLS libraries.
# MBEDTLS_VERSION - $major.$minor.$revision (e.g. ``2.6.0``).
#
# Hints:
#
# Set ``MBEDTLS_ROOT_DIR`` to the root directory of Mbed TLS installation.
