Rcl init failed to find shared library of rmw implementation

edit

Hi,

I installed ROS2 Dashing via the Debian package (desktop). The demo listener crashes after failing to find the Fast RTPS library (default RMW).

$ ros2 run demo_nodes_cpp listener
terminate called after throwing an instance of 'rclcpp::exceptions::RCLError'
