How to build integration test as cdylib?

[levitanus]

I have a library, which compiles to cdylib (lib_mylib.so) and being loaded by the app as plugin.
I want to test the library functions by the additional test cdylib (lib_test_mylib.so). But only approach I come to — is making a workspace with separate crate of test_mylib, that has integration test, that runs the app.

Is there a way to build lib_test_mylib.so as integration test step?

My crate structure:

lib.rs should build (*.so)
and run_test.rs should install *.so to app and run the app.

Currntly run_test.rs fails, as it can not find *.so of integration test.

Well, it seems, like you still need a separate crate to do so.
I've finished with a following test organization:

workspace_directory
├── Cargo.toml
├── README.md
├—— my_lib
├   ├—— src
│      └── lib.rs
└── test
    ├── Cargo.toml
    ├── src
    │   └── lib.rs
    └── tests
        └── integration_test.rs
