FindIce: New module to find ZeroC Ice
- autodetects Ice on all major platforms - allows building with all supported Visual Studio versions on Windows - autodetects the slice path on most platforms - separately detects the Ice programs, headers, slice files and libraries so that any Ice configuration or installation errors can be accurately reported, making diagnosis of Ice problems simpler

+# 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``, ``IceGrid``, ``IcePatch``, ``IceSSL``,
+# ``IceStorm``, ``IceUtil``, ``IceXML``, or ``Slice``.
+#
+# 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
+#
+# Ice programs are reported in::
+#
+# Ice_SLICE2CPP_EXECUTABLE - path to slice2cpp executable
+# Ice_SLICE2CS_EXECUTABLE - path to slice2cs executable
+# Ice_SLICE2FREEZEJ_EXECUTABLE - path to slice2freezej executable
+# Ice_SLICE2FREEZE_EXECUTABLE - path to slice2freeze executable
+# Ice_SLICE2HTML_EXECUTABLE - path to slice2html executable
+# Ice_SLICE2JAVA_EXECUTABLE - path to slice2java executable
+# Ice_SLICE2PHP_EXECUTABLE - path to slice2php executable
+# Ice_SLICE2PY_EXECUTABLE - path to slice2py executable
+# Ice_SLICE2RB_EXECUTABLE - path to slice2rb 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 :envvar:`ICE_HOME` may also be used; the
+# Ice_HOME variable takes precedence.
+#
+# 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.
