M1 Pro iOS lame 编译报错

iOS编译lame报错：

Building for 'iOS-simulator', but linking in object file (/Users/mac/.pub-cache/git/flutter_plugin_record-d11120b8be154e38c6e36fc895ec6ea8c612375c/ios/lame-ios.framework/lame-ios[arm64][2](VbrTag.o)) built for 'iOS'

这一看lame官网，好家伙，最后一个版本 2017 年发布的，你搁哪儿给我扯蛋呢？

编译 Apple 全平台的framework

编译真机 (arm64):

xcodebuild -project lame.xcodeproj \
  -sdk iphoneos \
  -arch arm64 \
  -configuration Release \
  build \
  CONFIGURATION_BUILD_DIR=../build/ios

编译模拟器 (x86_64 + arm64-simulator)

xcodebuild -project lame.xcodeproj \
  -sdk iphonesimulator \
  -arch x86_64 -arch arm64 \
  -configuration Release \
  build \
  CONFIGURATION_BUILD_DIR=../build/simulator

这样../build/ios 和../build/simulator里会各自生成一个静态库libmp3lame.a

回到项目根目录执行：

xcodebuild -create-xcframework \
  -library build/ios/libmp3lame.a \
  -headers include \
  -library build/simulator/libmp3lame.a \
  -headers include \
  -output build/lame-ios.xcframework

最终你会在build/目录得到：

lame-ios.xcframework

修改 flutter_plugin_record.podspec 配置

  s.description      = <<-DESC
