feat: ensure run exports

To trigger the different code paths, on checking the run_exports you can test it with:

# Using the latest build of `pixi-build-cmake` from your local path
> cd path/to/pixi-build-backend
> pixi run install-pixi-build-cmake

[workspace]
channels = ["https://prefix.dev/conda-forge"]
platforms = ["win-64", "linux-64", "osx-64", "osx-arm64"]
preview = ["pixi-build"]

[dependencies]
sdl_example = { path = "." }

[tasks.start]
cmd = "sdl_example"

[package]
name = "sdl_example"
version = "0.1.0"

[package.build]
backend = { name = "pixi-build-cmake", version = "0.1.*" }

[package.host-dependencies]
# This ensures that SDL2 is available at build time.
sdl2 = ">=2.26.5,<3.0"

PIXI_BUILD_BACKEND_OVERRIDE_ALL=1 pixi install

Now replace the https://prefix.dev/conda-forge with conda-forge
And now you'll be able to trigger the code path with different metadata resolving.

edit: for memory, this was the error we hit as the run_exports where not implemented for the new path:

not implemented: Extracting run exports from other places is not implemented yet
Error:   ⚠ failed to solve 'default' for osx-arm64
  ╰─▶ the operation was cancelled

Did you even test this @remimimimimi ?

The implementation is buggy, using @ruben-arts reproducer your code is not run. When I fix the flaws (as suggestions from this review), we reach unreachable code.

@ruben-arts Could you check this again? I run it locally, it's fixed!

@baszalmstra Hi, Bas. I think it's already fixed. Could you please check it again?

[baszalmstra]

You'll hit it instantly if you change the channel from https://prefix.dev/conda-forge to conda-forge.

I tested with the channels:

channels = [
  "https://prefix.dev/pixi-build-backends",
   "conda-forge",
]

It runs well on my machine. Or do I need to remove https://prefix.dev/pixi-build-backends?

This works now! 🚀
