#[=======================================================================[.rst:
Findcppzmq
---------
Find the C++ ZeroMQ library
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following imported targets, if found:
``cppzmq::cppzmq``
The C++ ZeroMQ library
``cppzmq::cppzmq-static``
The C++ ZeroMQ library
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``cppzmq_FOUND``
True if the system has the C++ ZeroMQ library.
``cppzmq_static_FOUND``
True if the system has the static C++ ZeroMQ library.
``cppzmq_IS_STTAIC``
True if ``cppzmq::cppzmq-static`` is the same as ``cppzmq::cppzmq``.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``cppzmq_INCLUDE_FILE``
The path to ``zmq.hpp`` file.
``cppzmq_INCLUDE_DIR``
The directory containing ``zmq.hpp``.
