# 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 slice programs are reported in::
#
#   Ice_SLICE2CPP_EXECUTABLE - path to slice2cpp executable

#   Ice_ICESTORMMIGRATE_EXECUTABLE - path to icestormmigrate executable
#
# 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_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.
