Hello, I am having a strange set of issues regarding the message filter. I am attempting to synchronize two stereo image topics and the code is relatively simple and has been checked with other sources from the internet. The code builds fine with colcon build but when I try to do ros2 run I get the error

symbol lookup error: undefined symbol: _ZN15message_filters10ConnectionC1ERKSt8functionIFvvEE`.

When I try to build it without colcon and use CLion's CMake configuration I get the following

message_filters::Connection message_filters::Signal9<sensor_msgs::msg::Image_<std::allocator<void> >, sensor_msgs::msg::Image_<std::allocator<void> >, message_filters::NullType, message_filters::NullType, message_filters::NullType, message_filters::NullType, message_filters::NullType, message_filters::NullType, message_filters::NullType>::addCallback<std::shared_ptr<sensor_msgs::msg::Image_<std::allocator<void> > > const&, std::shared_ptr<sensor_msgs::msg::Image_<std::allocator<void> > > const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&>(std::function<void (std::shared_ptr<sensor_msgs::msg::Image_<std::allocator<void> > > const&, std::shared_ptr<sensor_msgs::msg::Image_<std::allocator<void> > > const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&, std::shared_ptr<message_filters::NullType const> const&)> const&)':

I am not sure if the problems are related but either way I can not get my simple rclcpp node with a single message_filter time synchronizer to run. I am using ROS2 eloquent on Ubuntu 18.04. Any help is greatly appreciated.
