Nx caching inputs missing for all projects using `setupFiles` or `globalSetup` in `vitest.config.ts`

[BioPhoton]

Update:
We have to re-evaluate the issue after #1142 is merged

What happened?

If I change something in a testing lib the packages using them over setupFiles or globalSetup in vitest.config.ts have a false cache hit.

The problem:
Project models als all other projects miss the dependencies to testing files referenced in vitest.config.ts.

What would you expect to happen?

If I change something in a testing lib the packages using them over setupFiles or globalSetup in vitest.config.ts do not have a cache hit.

Possible Solutions:

• add implicitDependencies to all relevant testing targets - quick but not fine-grained also the biggest downside is our build and any other target in the project would be affected. ⚠️
• add the used files from vitest.config.ts as target inputs/namedInputs - fine-grained but only maintainable over custom plugin that adds the inputs. But as the used filse in setupFiles or globalSetup change it has to be dynamically detected.

What steps did you take?

1. ✅ Test the project modles in packages/models and verify cache hit

  # [existing outputs match the cache, left as is] <= ✅ this is correct. It should have a cache hit
   nx run models:unit-test

2. ✅ Apply any code change in the project testing-setup in folder testing/setup and save the change to your filesystem
3. ❌ Test the project modles in packages/models and verify NO cache hit - nx unit-test models

  # [existing outputs match the cache, left as is] <= ❌ this is not correct. It should not have a cache hit
   nx run models:unit-test
