Sorry, I dont have a computer to test, but here are a few thougts:

- if the libraries are picked at runtime using dlopen, autopatchelf can’t see them so you might need to use `runtimeDependencies`, and disable the optimisations on rpath, `dontPatchELF = true;`. See also [How to set `runtimeDependencies` for shared libraries? - #5 by tobiasBora](https://discourse.nixos.org/t/how-to-set-runtimedependencies-for-shared-libraries/14857/5)
- if the binary really expects lib to be in a subfolder, you can copy the whole program to `$out/opt` and add a wrapper (maybe a link would work as well) in `$out/bin` that calls stuff in `$out/opt`
