Research direction

Investigate the `generator` function implementation in the Meson source code, likely in `mesonbuild/interpreter.py` or similar. Understand how arguments are validated and modify the validation to allow executable targets (which are of type `BuildTarget`) instead of only strings. Also check existing tests for similar functionality to ensure no regressions.
