Compile examples undert FAST_DDS

edit

Hello all,

I tried to create the examples under src/eProsima/Fast-DDS as follow with the build command as below: colcon build --symlink --packages-select=fastrtps The compile result is success but the executable file HelloWorldExample isn't created.

Just wonder why and how to build those examples for a testing.

BTW， I am using the latest code of galactic which is cloned on 5,Dec.,2021.

Thanks a lot for any clues.
