I have an old application, EagleCAD, from 2014, a 32bit app, I managed to install it on my linux (Debian based, 64bits) and it works fine, but I had to look for and install some lib manually.
How can I package all this, the bin and libs, into one that I could easily re-install on about any distro? AppImage? Flatpak? Snap?

Most of these technologies combine some sort of sandboxing with the containerization part and the app has to be specifically adapted to use different ways to access data and system services where it needs to break the sandbox barrier.
