C++ Apple Mach-O链接器错误：架构armv7 Google Protobuf的未定义符号

我一直在从事一个包含两部分的项目：

一个静态库（.framework）

使用我的（.framework）静态库的演示应用程序

我了解到，添加到.framework（即opencv2.framework）中的任何.framework都必须添加到我的演示应用程序中。我还了解到，架构的构建设置必须相同，并且必须设置构建设置搜索路径

很高兴，我已经在演示应用程序中构建和使用.framework有一段时间了。最近，我在.framework中添加了Google协议缓冲区

我的.framework正在编译中，在.framework中似乎一切正常

当然，我的演示应用程序不是很满意

现在我已经将libprotobuf lite.a添加到我的演示应用程序中，并将路径添加到标题搜索路径中的标题文件中

这应该能奏效。但是，我收到了以下错误，到目前为止还没有找到答案。以下是错误日志：
