FindICU when used natively (i.e. without Android.cmake, compilation for
pc) uses PkgConfig. Old code would only check the first depedency
returned by PkgConfig as ${PC_ICU_${MOD_NAME}_LIBRARY} would already be
set for the remaing cycles, and no new find_library would be performed.
This resulted in libicui18n being included thrice, but depedencies uc
and data being ommited.
