The ros package ros-melodic-eigen-conversions seems to contain that .so as well. Please try to remove libtf-conversions-dev and install ros-melodic-eigen-conversions.

dpkg-query -L ros-melodic-eigen-conversions
/.
/opt
/opt/ros
/opt/ros/melodic
/opt/ros/melodic/include
/opt/ros/melodic/include/eigen_conversions
/opt/ros/melodic/include/eigen_conversions/eigen_kdl.h
/opt/ros/melodic/include/eigen_conversions/eigen_msg.h
/opt/ros/melodic/lib
/opt/ros/melodic/lib/libeigen_conversions.so
/opt/ros/melodic/lib/pkgconfig
/opt/ros/melodic/lib/pkgconfig/eigen_conversions.pc
...

The fix would then be to make eigen_conversions a run_depend in pilz_trajectory_generation.

Removed the libtf-conversions-dev package and installed ros-melodic-eigen-conversions. The solution works fine.
