why? one can freely use [`add_mlir_library`](https://github.com/llvm/llvm-project/blob/main/mlir/examples/standalone/lib/Standalone/CMakeLists.txt#L1) or [`add_mlir_public_c_library`](https://github.com/llvm/llvm-project/blob/main/mlir/examples/standalone/lib/CAPI/CMakeLists.txt#L1) downstream right?

does the `_deps` need to be a genex? If not you can just do [list/set difference](https://stackoverflow.com/a/59578250)?
