winit suddenly requires `cmake` dependency

[Jasper-Bekkers]

It looks like ever since sctk-adwaita got upgraded (and their dependencies got upgraded) this crate is dragging in cmake, polluting everybody's build system and setup. Our project has a zero-tolerance policy for cmake (or other build time tools since we just want to be able to build trough cargo with no additional tools required to be set up).

Dependency tree seems to be:

sctk-adwaita ->crossfont -> servo-fontconfig -> servo-fontconfig-sys -> expat-sys -> cmake

Presumably all of this isn't strictly required and can be disabled?

Just disable sctk-adwaita feature? Or install system headers for fontconfig, freetype?

Honestly if sctk-adwaita drags in such major dependencies, I don't think it should be enabled by default

The point to have decorations that make sense on Wayland. Like you know, that you will have a text in your title bar. That's the main point to provide sensible defaults. Otherwise you'll be surprised that your window suddently doesn't have a title bar or actual buttons.

If anything we can abort compilation if you don't have system library headers installed.

[Jasper-Bekkers]

I don't think any of that is needed, sensible titlebars are very welcome, however, that can all be achieved without reliance on cmake (and by having a sensible build setup).

[kchibisov]

Well, bring it to whoever builds those system crates and requires to put the entire thing just to build it just in case?

I'll alter to just abort. So you won't have a cmake problem.

On alternative might be to swap out servo-fontconfig with fontconfig/yeslogic-fontconfig, which doesn't fall back to vendoring fontconfig and expat when it can't find a compatible version of fontconfig at build time, but that's a decision to make for whoever is maintaining crossfont.

Servo does the same thing. That's the point. The issue is that it fallbacks. We have a flag in crossfont to not ever fallback here, which is what they want. I've patched sctk-adwaita to use that flag instead, but it'll have time for it to release.

It's alacritty's project, so it's kind of me.

Reopening since we want to force system libraries.
