# This CMake file builds ICU.
# We build:
# - libicustubdata.a, a stub library for data, which we don't use.
# - libicui18n.a, the internationalization library.
# - libicuuc.a, a common utility library.
#
# To save some space and time, we have removed directories which are not
# needed by MySQL:
#   source/allinone
#   source/config
#   source/data
#   source/extra
#   source/layoutex
#   source/samples
