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
ICU_LIBRARIES - component libraries to be linked
ICU_VERSION - ICU release version

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::
