Skia vulkan renderer feature doesn't work.

[GRX005]

Bug Description

Upon selecting the skia vulcan renderer feature in cargo.toml like this:
[dependencies]
slint = { version = "1.11.0", features = [
"backend-winit", # enable winit for windowing
"renderer-skia", # core Skia support (OpenGL/Metal/D3D/Software)
"renderer-skia-vulkan", # force Vulkan path
] }

It won't compile and will throw this error:
error: failed to run custom build command for skia-bindings v0.84.0
note: To improve backtraces for build dependencies, set the CARGO_PROFILE_DEV_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.

Environment Details

• Slint Version: 1.11.0
• Platform/OS: Windows 11
• Programming Language: Rust
• Backend/Renderer: Skia

Product Impact

I want to build a windows 11 native mod manager for a game.
I'd prefer to use vulcan for the UI as the opengl renderer makes the fonts ugly as said in the docs.

can't download skia-binary; You can download the compiled files from GitHub by yourself. And then, configure environment variables ''' SKIA-BINARIES_URL''' Value: file://D:/AppInstall/Skia/skia-binaries-8df1749a67a2800c2904-x86_64-pc-windows-msvc-d3d-gl-textlayout-vulkan.tar.gz

This method can solve your problem

Skia compilation can sometimes be problematic (and that's the reason it is not the default)

It tries to download the binary for your platform, but if that binary is not found for the specific platform you are building for (which is the case for you) it will try to make a compilation.

We have a guide with the most common compilation errors there:
https://docs.slint.dev/latest/docs/slint/guide/backends-and-renderers/backends_and_renderers/#skia-renderer

Please paste the actual compile error so we can help you to compile Skia. (your log was cut before the actual error)
