my .build.sh

#!/bin/bash
cmake -DCMAKE_BUILD_TYPE=Release  "-DCMAKE_PREFIX_PATH=/usr/lib/llvm-14"  -DCMAKE_INSTALL_PREFIX=../install ../SkottieWrapper

after i exec .build.sh, i exec make Build_Skia
then i encounter the issue:

Is aarch64 added to the cpu list by yourself?

[liurunjieDW]

'aarch64': 'arm64'

yes i added 'aarch64': 'arm64' to the cpu list ,if it wasn't ,
you would encouter the issue,

Does it works fine?
I think this is an issue of ICU or gn, you can report the issue to upstream,
maybe I will make a patch then apply it when build running
