OMPL for Motion Planning build error

[anoopsonar30]

Hi! I installed Open3D, OMPL and OpenMP but am still running into this error while building flightros with motion planning using OMPL.

Errors     << flightros:make /home/snoop/catkin_ws/logs/flightros/build.make.063.log

It seems like a linking error and I've tried editing the CMakeLists.txt but it still fails with the same errors. The linker is failing not just on ompl functions but also on the ros functions so I'm not sure what the problem is.
