具体如下：
2 directories, 11 files
root@a8acaabb5d7b:/home/builder/cyberdog_ws/audio_demos# cd ..
root@a8acaabb5d7b:/home/builder/cyberdog_ws# colcon build --merge-install --install-base /opt/ros2/cyberdog/ --packages-up-to audio_demos
Starting >>> audio_demos
--- stderr: audio_demos
CMake Error at CMakeLists.txt:15 (find_package):
By not providing "Findprotocol.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "protocol",
but CMake did not find one.

Could not find a package configuration file provided by "protocol" with any
of the following names:

protocolConfig.cmake
protocol-config.cmake

Add the installation prefix of "protocol" to CMAKE_PREFIX_PATH or set
"protocol_DIR" to a directory containing one of the above files. If
"protocol" provides a separate development package or SDK, be sure it has
been installed.
