# ICU_FOUND - True if ICU found.
# ICU_I18N_FOUND - True if ICU's internationalization library found.
# ICU_INCLUDE_DIRS - Directory to include to get ICU headers
# Note: always include ICU headers as, e.g.,
# unicode/utypes.h
# ICU_LIBRARIES - Libraries to link against for the common ICU
# ICU_I18N_LIBRARIES - Libraries to link against for ICU internationaliation
