#  ARROW_FLIGHT_FOUND, whether Flight has been found
#  ARROW_FLIGHT_IMPORT_LIB,
#    path to libarrow_flight's import library (Windows only)
#  ARROW_FLIGHT_INCLUDE_DIR, directory containing headers
#  ARROW_FLIGHT_LIBS, deprecated. Use ARROW_FLIGHT_LIB_DIR instead
#  ARROW_FLIGHT_LIB_DIR, directory containing Flight libraries
#  ARROW_FLIGHT_SHARED_IMP_LIB, deprecated. Use ARROW_FLIGHT_IMPORT_LIB instead
#  ARROW_FLIGHT_SHARED_LIB, path to libarrow_flight's shared library
