# 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 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.
