| # 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. |
