Building robot_localization pkg error with yaml-cpp target not found

[iyhabz]

Hey i am trying to build the robot_localization pkg and keep having the error regarding the yaml-cpp pkg

CMake Error at CMakeLists.txt:82 (add_executable):
  Target "ekf_node" links to target "yaml-cpp::yaml-cpp" but the target was
  not found.  Perhaps a find_package() call is missing for an IMPORTED
  target, or an ALIAS target is missing?

has any one faced an issue like this?

thanks in advance

Hello,
You need to tell your CMake file where is the yaml-cpp library in order to successfully build the ROS robot_localization package.
The README of this repository give an explanation on how to include the yaml-cpp library to your C++ project here.
You can add this before the find_package() of your CMake file (don't forget to speciffy the GIT_TAG argument).

[b-adkins]

The dynmsg package in dynamic_message_introspection has an example of how to include yaml-cpp in a ROS2 package. You might want to check that out.

[annanya-tamu]

Are you sure you are using the correct branch of robot_localization? Switching to humble-devel instead of ros2 worked for me in resolving this issue.
