MacOS环境下Unity使用OVRLipSync遇DllNotFoundException问题求助

已确认脚本后端设置为ILCPP，求解决办法。

解决办法 #

• 检查插件DLL完整性：确认Assets/Oculus/LipSync/Plugins目录下存在MacOS平台对应的libOVRLipSync.dylib文件，若缺失，重新下载并导入完整的Oculus Integration包。
• 配置DLL平台属性：选中该DLL文件，在Inspector面板中勾选macOS平台，将CPU架构设置为Universal（适配Intel和Apple Silicon），确保"Include in Build"选项处于勾选状态。
• 核对ILCPP架构设置：进入Unity的Player Settings > Other Settings > Configuration，确认ILCPP的Target Architectures勾选了当前Mac设备对应的架构（Intel 64-bit和/或Apple Silicon）。
• 清理项目缓存：删除项目根目录下的Library文件夹，重启Unity后重新生成项目文件，再尝试运行或构建。
• 验证版本兼容性：确保使用的Oculus Integration包与当前Unity版本兼容，避免因版本不匹配导致的DLL加载异常。
