Your CMake installs you binary to bin, but ros2 run only looks in the "libexec" folder (actually `lib/pkg`) for executables. Your binary is just on the PATH, so you don't need ros2 run to easily execute it. See our examples for how to install to libexec: https://github.com/ros2/examples/blob/9a819e007c13a5fb243641d300d6300306750cb0/rclcpp/minimal_publisher/CMakeLists.txt#L26 --- [Visit Topic](https://discourse.ros.org/t/cannot-run-executable-and-lib-using-ros2-run-after-building-using-ament/2640/2) or reply to this email to respond.
