Suggested solutions

As the distributed logger component is included in the top-level CMakeLists.txt, we need to check whether the version is greater than 6.1.0, to filter them out. See comment

iblancasa commented 3 years ago

The problem is that it will not be possible to build those examples as standalone. The -Wl,--no-as-needed are added because we are enabling the distributed_logger component at the top level CMakeLists.txt. So, it is not a good idea to remove them (probably, since those flags are not needed from 6.1.0, we can add or not them depending on the ConnextDDS version)
