Hi, I have an idea to solve this:
https://github.com/apache/arrow/pull/8166#pullrequestreview-486396454 > It'll be fixed by using system c-ares (installed by > Homebrew) in both Apache Arrow and gRPC. We need > c-ares-config.cmake for it. The current > https://github.com/Homebrew/homebrew-core/blob/master/Formula/c-ares.rb > uses configure and make. We'll be able to install > c-ares-config.cmake by switching to cmake and ninja from > configure and make.
