FindIce
-------

.. versionadded:: 3.1

Finds the Internet Communication Engine (Ice) programs, libraries and datafiles.
Ice is an open-source remote procedure call (RPC) framework developed by ZeroC
and provides SDKs for various languages to develop network applications.

.. versionadded:: 3.4
  Imported targets for components and many new ``*_EXECUTABLE`` variables.

.. versionadded:: 3.7
  Debug and Release library variants are found separately.

.. versionadded:: 3.10
  Ice 3.7 support, including new components, programs and the Nuget package.

Components
^^^^^^^^^^

Ice consists of several libraries and programs (executables).  This find module
supports components, which can be specified using the :command:`find_package`
command, to select specific Ice libraries for use in a CMake project.
Executables provided by Ice installation are always searched automatically,
regardless of the specified components.

The list of available components depends on the Ice version in use.  To
successfully find Ice, at least one component must be specified:

.. code-block:: cmake

  find_package(Ice COMPONENTS <components>...)

Supported components include:

.. hlist::

  - ``Freeze``
  - ``Glacier2``
  - ``Ice``
  - ``IceBox``
  - ``IceDB``
  - ``IceDiscovery``
  - ``IceGrid``
  - ``IceLocatorDiscovery``
  - ``IcePatch``
  - ``IceSSL``
  - ``IceStorm``
  - ``IceUtil``
  - ``IceXML``
  - ``Slice``

Ice 3.7 and later also include C++11-specific components:

.. hlist::

  - ``Glacier2++11``
  - ``Ice++11``
  - ``IceBox++11``
  - ``IceDiscovery++11``
  - ``IceGrid++11``
  - ``IceLocatorDiscovery++11``
  - ``IceSSL++11``
  - ``IceStorm++11``

Imported Targets
^^^^^^^^^^^^^^^^

This module provides the following :ref:`Imported Targets`:

``Ice::<component>``
  .. versionadded:: 3.4

  Target encapsulating the usage requirements for the specified Ice component
  (library), available if that component is found.  The ``<component>`` should
  be written in the same case, as listed above.  For example, use
  ``Ice::Glacier2`` for the Ice Glacier2 library, or ``Ice::Ice++11`` for the
  Ice++11 library, etc.

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

``Ice_FOUND``

  components for using Ice were found.

Cache Variables
^^^^^^^^^^^^^^^

  executables.

``Ice_INCLUDE_DIR``

  The data directory containing interface definitions for Slice.

``Ice_<COMPONENT>_LIBRARY``
  The path to the library for the specified component.  The ``<COMPONENT>``
  should be written in uppercase.

Hints
^^^^^

This module accepts the following variables:

``Ice_HOME``
  Set this CMake variable to the root of the Ice installation in order to
  search for Ice in a custom location.

  .. note::

    On Windows, Ice 3.7.0 and later provide libraries via the NuGet
    package manager.  Appropriate NuGet packages will be searched for
    using :variable:`CMAKE_PREFIX_PATH`, or alternatively ``Ice_HOME`` may be
    set to the location of a specific NuGet package to restrict the search.

``ICE_HOME``
  Environment variable (uppercased) may also be set to the root of the Ice
  installation;  The ``Ice_HOME`` CMake variable takes precedence.

``Ice_DEBUG``
  Set this variable to boolean true to enable debug output from this module.

.. note::

  In most cases, none of the above variables need to be set unless multiple Ice
  versions are installed and a specific one is required.  On Windows, the most
  recent version is typically found using the registry.  On Unix-like systems,
  programs, headers, and libraries are usually found in standard locations,
  although ``Ice_SLICE_DIRS`` might not be detected automatically (commonly
  known locations are searched).  All other variables default based on the value
  of ``Ice_HOME``, if set.

  It's also possible to set ``Ice_HOME`` while selectively overriding specific
  locations for individual components;  This might be required, for example, in
  newer versions of Visual Studio if the heuristics are not sufficient to
  identify the correct programs and libraries for the specific Visual Studio
  version.
