c++ - Catkin 构建在构建时失败。未定义对 YAML 错误的引用

Question

我在尝试构建项目时收到以下错误。

我的 CMake 文件包括以下内容

#Yaml
find_package(yaml-cpp)
#Project Executables(Nodes)
add_executable(learning_node_diagnostics 
 src/learning_node_diagnostics.cpp
)
target_include_directories(learning_node_diagnostics PRIVATE include)
target_link_libraries(learning_node_diagnostics PUBLIC 
learninglib
${PCL_LIBRARIES}
${catkin_LIBRARIES}
${OpenCV_LIBS}
${YAML_CPP_LIBRARIES}
)
...

而且我还尝试了以下作为我的 CMake 文件并得到了同样的错误

find_package(PkgConfig)
pkg_check_modules(YAMLCPP REQUIRED yaml-cpp>=0.5)
include_directories(${YAMLCPP_INCLUDE_DIRS})

add_executable(name src/name.cpp)
target_link_libraries(name ${catkin_LIBRARIES}  ${YAMLCPP_LIBRARIES})

我也尝试过以下 CMake 文件

#Yaml
find_package(yaml-cpp REQUIRED)
target_link_libraries(name ${catkin_LIBRARIES}  yaml-cpp)

它们似乎都不起作用，我知道该项目是在其他计算机中构建的，并且 yaml 似乎可以在我的计算机上使用 moveit api 正常工作。我已经尝试重新安装 ROS Noetic，但它仍然无法正常工作。这个时候我能做什么。我使用的是 Ubuntu 20.04，并且安装了 ROS Noetic 发行版。
