# OPC UA Discovery — Top-level build
# ======================================
#
# Builds three programs that demonstrate OPC UA discovery. ServerLDS runs a
# Local Discovery Server.  ServerRegister periodically registers itself with the
# LDS.  Client queries servers for discovery info, endpoints, or current time.
#
# All programs link against common (shared helpers and config parser)
# which in turn depends on open62541.

# Each test exercises a combination of security mode/policy and authentication
# method.  _test_names and _test_policies are parallel lists: the Nth name uses
# the Nth policy.  Each name corresponds to a config directory under tests/
# containing server_lds.conf, server_register.conf, server_register_client.conf,
# client.conf.
