I built Ofelia external on Ubuntu 18.04 LTS and it seems like the binary is incompatible in newer Ubuntu and some other distros.

Maybe you could try something like the following script which I found from this post: https://forum.openframeworks.cc/t/building-executables-that-run-in-the-future-after-updating-shared-libraries/28542

If this doesn't work, I would suggest building the external yourself following the instruction from: https://github.com/cuinjune/ofxOfelia#build-requirements

I will try to make Ofelia binary work across different versions and distros in the close future. If anyone has a good idea to do this, please let me know.

Best
