[bug] inconsistency between nsis and wix bundle

[mayocream]

Describe the bug

The Wix bundles all binaries in the target/release folder, including DLLs; while nsis doesn't.

https://github.com/tauri-apps/tauri/blob/1c53640ac3d05650fdf8db6da9b04d594491dd54/crates/tauri-bundler/src/bundle/windows/msi/main.wxs#L156-L160

Reproduction

Add ort = { version = "=2.0.0-rc.9", features = ["cuda"] to Cargo.toml.

ort will download the ONNXRuntime DLLs and copy them to target/debug.

Then run bun tauri build.

Expected behavior

The behavior between nsis and wix should be consistent.

you're right and it's a known issue. the wix bundler's behavior is considered wrong so we didn't add it to the nsis one. but changing it in the wix bundler would kindaaa be a breaking change so we have to live with it for now.
