C++项目使用Homebrew安装的Protobuf编译链接时Abseil相关符号未定义的问题求助

我正在尝试在自己的应用中使用Protobuf，现在需要完成链接步骤来运行程序。

已执行的操作步骤 #

1. 通过Homebrew安装Protobuf：

   brew install protobuf
   

2. 检查Abseil是否已安装（因为遇到了相关错误）：

   brew list --versions abseil
   

3. 更新了链接器命令，使用的编译命令如下：

   /usr/bin/g++ -std=c++17 -fdiagnostics-color=always -I/Users/me/dev/customDev/cpp/tiny_db/generated -g /Users/me/dev/customDev/cpp/tiny_db/include/tiny_db.pb.cc /Users/me/dev/customDev/cpp/tiny_db/main.cpp -o /Users/me/dev/customDev/cpp/tiny_db/main -lprotobuf
   

4. 编译proto文件：

   protoc --cpp_out=./include tiny_db.proto
   

5. 在main.cpp中引入了生成的头文件，代码片段如下：

   #include <iostream>
   #include <unordered_map>
   #include <vector>
   #include <stdexcept>
   #include <fstream>
   #include "include/tiny_db.pb.h"
   

遇到的错误 #

执行编译命令后出现了x86_64架构下的符号未定义错误：

clang: error: linker command failed with exit code 1 (use -v to see invocation)

后续尝试的问题 #

我尝试添加Abseil相关的链接库参数：-labsl_base -labsl_log_internal -labsl_strings -labsl_log_severity，但编译时提示：

ld: library 'absl_log_internal' not found

我确认了Abseil是随Protobuf自动安装的，版本为abseil 20240722.0。

我的疑问 #

请问我该如何正确编译我的C++文件？

编辑补充：我看到过相关的问题讨论，但不想从源码编译Protobuf，希望能找到更便捷的解决方式。
