installation failure Imported target "g2o::solver_eigen" includes non-existent path

I tried to compile the code using the command

colcon build --symlink-install --cmake-clean-first --parallel-workers 12 --ament-cmake-args -DPYTHON_EXECUTABLE=$MY_PYTHON_ENV

I keep on getting this error message

`This may be promoted to an error in a future release of colcon-override-check. Starting >>> lidarslam_msgs Starting >>> ndt_omp_ros2 Starting >>> ros2_kitti_publishers Starting >>> turtlesim Finished <<< lidarslam_msgs [15.5s]

CMake Error in CMakeLists.txt: Imported target "g2o::solver_eigen" includes non-existent path

"/usr/local/include/g2o/solver_eigen"

in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:

• The path was deleted, renamed, or moved to another location.

• An install or uninstall procedure did not complete successfully.

• The installation package was faulty and references files it does not provide.

Perhaps you compile and install g2o? If you are, that's the problem, install ros--libg2o with apt.
