find_package(Boost) may pass file paths for Boost libraries which may not be present in the default search locations at link time, so target_link_libraries(... boost_program_options) may not always work.
Since FindBoost.cmake sets Boost_<C>_FOUND and Boost_<C>_LIBRARIES for each requested component, we can let ament_target_dependencies() discover the component as if it were a standalone package.
