error: unable to find library -lunwind

[hpelitebook745G2]

1. Cloned didkit and ssi in the same level in a folder
2. Ran cargo build in the didkit root folder
3. Ran cd ./lib
4. Ran make ../target/test/android.stamp

Got this error:

error: linking with `i686-linux-android19-clang` failed: exit status: 1

error: could not compile `didkit` (lib) due to previous error

I ran brew install lunwind:

➜  lib git:(main) ✗ brew install lunwind

To install luabind, run:

I ran brew install luabind:

I ran brew install libunwind:
