FindIce
-------

Find the ZeroC Internet Communication Engine (ICE) programs,
libraries and datafiles.

This module supports multiple components.
Components can include any of: ``Freeze``, ``Glacier2``, ``Ice``,
``IceBox``, ``IceDB``, ``IceDiscovery``, ``IceGrid``,
``IceLocatorDiscovery``, ``IcePatch``, ``IceSSL``, ``IceStorm``,
``IceUtil``, ``IceXML``, or ``Slice``.

Ice 3.7 and later also include C++11-specific components:
``Glacier2++11``, ``Ice++11``, ``IceBox++11``, ``IceDiscovery++11``
``IceGrid``, ``IceLocatorDiscovery++11``, ``IceSSL++11``,
``IceStorm++11``

Note that the set of supported components is Ice version-specific.

This module reports information about the Ice installation in
several variables.  General variables::

  Ice_VERSION - Ice release version
  Ice_FOUND - true if the main programs and libraries were found
  Ice_LIBRARIES - component libraries to be linked
  Ice_INCLUDE_DIRS - the directories containing the Ice headers
  Ice_SLICE_DIRS - the directories containing the Ice slice interface
                   definitions

Imported targets::

  Ice::<C>

Where ``<C>`` is the name of an Ice component, for example
``Ice::Glacier2`` or ``Ice++11``.

Ice db programs (Windows only; standard system versions on all other
platforms) are reported in::

  Ice_DB_ARCHIVE_EXECUTABLE - path to db_archive executable
  Ice_DB_CHECKPOINT_EXECUTABLE - path to db_checkpoint executable
  Ice_DB_DEADLOCK_EXECUTABLE - path to db_deadlock executable
  Ice_DB_DUMP_EXECUTABLE - path to db_dump executable
  Ice_DB_HOTBACKUP_EXECUTABLE - path to db_hotbackup executable
  Ice_DB_LOAD_EXECUTABLE - path to db_load executable
  Ice_DB_LOG_VERIFY_EXECUTABLE - path to db_log_verify executable
  Ice_DB_PRINTLOG_EXECUTABLE - path to db_printlog executable
  Ice_DB_RECOVER_EXECUTABLE - path to db_recover executable

  Ice_DB_VERIFY_EXECUTABLE - path to db_verify executable
  Ice_DUMPDB_EXECUTABLE - path to dumpdb executable
  Ice_TRANSFORMDB_EXECUTABLE - path to transformdb executable

Ice component libraries are reported in::

  Ice_<C>_FOUND - ON if component was found
  Ice_<C>_LIBRARIES - libraries for component

Note that ``<C>`` is the uppercased name of the component.

This module reads hints about search results from::

  Ice_HOME - the root of the Ice installation

The environment variable ``ICE_HOME`` may also be used; the
Ice_HOME variable takes precedence.

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

The following cache variables may also be set::

  Ice_<P>_EXECUTABLE - the path to executable <P>
  Ice_INCLUDE_DIR - the directory containing the Ice headers
  Ice_SLICE_DIR - the directory containing the Ice slice interface
                  definitions
  Ice_<C>_LIBRARY - the library for component <C>

.. note::

  In most cases none of the above variables will require setting,
  unless multiple Ice versions are available and a specific version
  is required.  On Windows, the most recent version of Ice will be
  found through the registry.  On Unix, the programs, headers and
  libraries will usually be in standard locations, but Ice_SLICE_DIRS
  might not be automatically detected (commonly known locations are
  searched).  All the other variables are defaulted using Ice_HOME,
  if set.  It's possible to set Ice_HOME and selectively specify
  alternative locations for the other components; this might be
  required for e.g. newer versions of Visual Studio if the
  heuristics are not sufficient to identify the correct programs and
  libraries for the specific Visual Studio version.

Other variables one may set to control this module are::

  Ice_DEBUG - Set to ON to enable debug output from FindIce.
