error: Uncaught TypeError: LoadLibraryExW failed

[rishavs]

When I try to use the npm library https://github.com/ApsarasX/llvm-bindings in Deno, I faced 2 issues;

1. The Deno bindings generator was unable to compile a binary .node file for the npm library
2. when I copied the compiled binary from another npm project, I ended up with another error

At first the Deno bindings were unable to generate the .node bindings that this library is supposed to compile down to.

Since I was using the same lib in a node+esbuild project, I just copied the .node file to the bindings/Release directory.
This fixed the issue about being unable to find the binary bindings.

When I tried to run the project again, I got this error.

The Deno bindings generator was unable to compile a binary .node file for the npm library

This is most likely due to missing support for "postinstall" scripts (tracked in #16164)

when I copied the compiled binary from another npm project, I ended up with another error

I need to track this down, looks like a problem loading a native extension via dlopen.

Same issue for https://github.com/slint-ui/slint on windows

linux works

[ninjadev64]

Any solutions? I'm getting this using the Tauri CLI. Deno on Linux and Node on Windows both work.
