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:


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

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>


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.
