Mac环境，使用cmake编译DMKit出现异常

执行日志如下：

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.

Update the VERSION argument value or use a ... suffix to tell
CMake that the project does not need compatibility with older versions.

CMake Error at CMakeLists.txt:20 (message):
Fail to find brpc

brpc已完成安装。在unit-dmkit-master的根目录下。
执行sh deps.sh mac命令完成，且未报错。

Start with CMakeLists.txt, especially line 20 where the brpc check fails, and review how the dependency installed by sh deps.sh mac is discovered. Reproduce the configuration on macOS and compare the expected brpc location with CMake's search behavior. Done means CMake finds the installed brpc and proceeds past this error.
