# FindICU

New in version 3.7.

Find the International Components for Unicode (ICU) libraries and programs.

This module supports multiple components. Components can include any of: `data`, `i18n`, `io`, `le`, `lx`, `test`, `tu` and `uc`.

Note that on Windows `data` is named `dt` and `i18n` is named `in`; any of the names may be used, and the appropriate platform-specific library name will be automatically selected.

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

    ICU_VERSION - ICU release version
    ICU_FOUND - true if the main programs and libraries were found
    ICU_LIBRARIES - component libraries to be linked
    ICU_INCLUDE_DIRS - the directories containing the ICU headers

Imported targets:

    ICU::<C>

Where `<C>` is the name of an ICU component, for example `ICU::i18n`.

ICU programs are reported in:

    ICU_GENCNVAL_EXECUTABLE - path to gencnval executable
    ICU_ICUINFO_EXECUTABLE - path to icuinfo executable
    ICU_GENBRK_EXECUTABLE - path to genbrk executable
    ICU_ICU-CONFIG_EXECUTABLE - path to icu-config executable
    ICU_GENRB_EXECUTABLE - path to genrb executable
    ICU_GENDICT_EXECUTABLE - path to gendict executable
    ICU_DERB_EXECUTABLE - path to derb executable
    ICU_PKGDATA_EXECUTABLE - path to pkgdata executable
    ICU_UCONV_EXECUTABLE - path to uconv executable
    ICU_GENCFU_EXECUTABLE - path to gencfu executable
    ICU_MAKECONV_EXECUTABLE - path to makeconv executable
    ICU_GENNORM2_EXECUTABLE - path to gennorm2 executable
    ICU_GENCCODE_EXECUTABLE - path to genccode executable
    ICU_GENSPREP_EXECUTABLE - path to gensprep executable
    ICU_ICUPKG_EXECUTABLE - path to icupkg executable
    ICU_GENCMN_EXECUTABLE - path to gencmn executable

ICU component libraries are reported in:

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

ICU datafiles are reported in:

    ICU_MAKEFILE_INC - Makefile.inc
    ICU_PKGDATA_INC - pkgdata.inc

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

This module reads hints about search results from:

    ICU_ROOT - the root of the ICU installation

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

The following cache variables may also be set:

    ICU_<P>_EXECUTABLE - the path to executable <P>
    ICU_INCLUDE_DIR - the directory containing the ICU headers
    ICU_<C>_LIBRARY - the library for component <C>

Note

In most cases none of the above variables will require setting, unless multiple ICU versions are available and a specific version is required.

Other variables one may set to control this module are:

    ICU_DEBUG - Set to ON to enable debug output from FindICU.
