Libatomic1 package

Newcomer here. I need some help with an ARMv7l embedded system dependency issues.
I found this package here

But there are no .ipk files. There is a source and even in that there no actual source code files.
I was hoping to find .ipk files for various architectures (something like nodejs does).
BTW, this whole thing started because I needed to install nodejs on an armv7l and seems after nodejs version after 11.15.0 complain about libatomic1 dependency.

What am I missing? Could someone please help?

Since you didn't write what your target platform/architecture is I can't link directly, but for ath79 23.05 it's at, so definitely there, just adapt the link for your target.
