# FindZeroMQ
# ----------
#
# Find the ZeroMQ messaging support library.
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` target:
#
# ``ZeroMQ::ZeroMQ``
# The ZeroMQ library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``ZeroMQ_INCLUDE_DIR``
# where to find zmq.h, etc.
# ``ZeroMQ_LIBRARIES``
# the libraries to link against to use zmq.
# ``ZeroMQ_FOUND``
# If false, do not try to use ZeroMQ.
