====================================================================
【你只需要改这 2 个地方】（或改成导出环境变量也行）

1) KP_DIR：KernelPatch 源码目录（必须是绝对路径）
   例：/Users/<username>/Desktop/GithubProject/SVC_Call/KernelPatch

2) ANDROID_SDK：Android SDK 目录（必须是绝对路径）
   例：/Users/<username>/Library/Android/sdk

可选：
3) JAVA_HOME：JDK 17 的 Contents/Home（如果系统找不到会要求你手动设置）
   例：/Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home

不想改文件的话，也可以直接在终端执行：
  export KP_DIR=".../KernelPatch"
  export ANDROID_SDK=".../Android/sdk"
  export JAVA_HOME=".../jdk17/Contents/Home"   # 如需要
  bash build.sh
