CMake Warning at /opt/ros/melodic/share/catkin/cmake/catkin_package.cmake:166 (message): catkin_package() DEPENDS on 'yaml-cpp' but neither 'yaml-cpp_INCLUDE_DIRS' nor 'yaml-cpp_LIBRARIES' is defined. Call Stack (most recent call first): /opt/ros/melodic/share/catkin/cmake/catkin_package.cmake:102 (_catkin_package) qingzhou_odom/imu_calibrate/imu_calib/CMakeLists.txt:17 (catkin_package)

这是一个 CMake 警告，它告诉你的是你的 catkin_package() 依赖于 'yaml-cpp'，但是你没有定义 'yaml-cpp_INCLUDE_DIRS' 或 'yaml-cpp_LIBRARIES'。这通常意味着你需要在你的工作空间或系统中安装 yaml-cpp 库，或者将其添加到你的依赖项中。你可以通过以下命令在 Ubuntu 系统上安装 yaml-cpp 库：

sudo apt-get install libyaml-cpp-dev

如果你已经安装了 yaml-cpp 库，你需要确保你的 CMakeLists.txt 文件中包含以下行：

find_package(yaml-cpp REQUIRED)
include_directories(${yaml-cpp_INCLUDE_DIRS})

并且在你的 catkin_package() 中添加以下行：

CATKIN_DEPENDS yaml-cpp

这应该解决这个警告。

出现错误：CMake Error at /opt/ros/melodic/share/catkin/cmake/catkin_package.cmake:116os/melodic/share/catkin/cmake/catkin_package.cmake:100

这个错误是由CMake在构建ROS项目时出现的。根据错误信息，可能是在catkin_package.cmake文件的第116行或第100行出现了问题。

要解决这个错误，可以尝试以下几个步骤：
1. 检查CMakeLists.txt文件中是否有语法错误或者缺少必要的依赖项。
2. 确保你的ROS环境正确安装并设置好了。
3. 检查catkin_package.cmake文件的相关行，看看是否有错误或者缺少必要的参数。

如果以上步骤都没有解决问题，可以尝试搜索相关错误信息，查看其他人是否遇到过类似的问题，并找到解决方案。
