I rebuilt oatpp and the example-hls-media-stream on the the target board (Aarch64 Nvidia Jetson Xavier). I ran all the tests and performed a similar test on example-hls-media-stream that was causing SIGABRT on my code. Everything works fine and no SIGABRT.
I'll assume that something in my code or cmake is doing it. My next goal would be to integrate into my code (with minimum changes) and repeat the tests. This issue can be closed for now.
