新款Mac Mini上CMake无法定位JNI包的技术求助

在新款ARM64架构的Mac Mini上运行CMake时，无法定位JNI包，但相同的CMake配置在旧款MacBook Pro、Windows及多种Linux系统上均可正常工作。已尝试设置CMAKE_FIND_FRAMEWORK=never，但无任何效果。

环境信息 #

• CMake版本：3.26.3
• Java版本：

java version "20.0.1" 2023-04-18
Java(TM) SE Runtime Environment (build 20.0.1+9-29)
Java HotSpot(TM) 64-Bit Server VM (build 20.0.1+9-29, mixed mode, sharing)

• 系统版本：

Darwin  22.4.0 Darwin Kernel Version 22.4.0: Mon Mar  6 21:01:02 PST 2023; 
root:xnu-8796.101.5~3/RELEASE_ARM64_T8112 arm64

• JAVA_HOME：/Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home
• JNI头文件存在验证：

ls -l /Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home/include/jni.h
-rw-r--r--  1 root  wheel  74986 Mar  7 09:13 /Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home/include/jni.h

可行解决思路 #

• 手动指定JNI路径：在CMake命令行或CMakeLists.txt中直接设置JNI相关路径，绕过自动查找逻辑：
  命令行方式：

  cmake .. -DJAVA_INCLUDE_PATH=/Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home/include -DJAVA_INCLUDE_PATH2=/Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home/include/darwin
  

  CMakeLists.txt方式（添加在find_package(JNI)之前）：

  set(JAVA_INCLUDE_PATH "/Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home/include")
  set(JAVA_INCLUDE_PATH2 "/Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home/include/darwin")
  

• 升级CMake版本：CMake 3.26可能对ARM64 macOS的JNI路径识别存在兼容性问题，尝试升级到3.27及以上版本，新版本可能修复了ARM架构下的查找逻辑。

• 确保环境变量正确传递：运行CMake前显式导出JAVA_HOME，避免CMake无法读取该变量：

  export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-20.jdk/Contents/Home
  cmake ..
