Nixpkgs version

• Stable (25.05)

Describe the bug

The libraries nix file compresses all the .step files, and removes the originals. The effect of this is that KiCAD projects created on NixOS don't show models when shared with other people.

Steps to reproduce

• Install KiCAD
• Created a PCB
• share KiCAD project with someone not on nixos and have them open it.
• The 3D view on their version won't show any of the 3d models.

Expected behaviour

I expect projects I create in KiCAD to work on other installs of KiCAD, as is.

Screenshots

Relevant log output

Additional context

Please remove this, or at least make it a configuration option.

I am trying to cooperate on several projects, and whenever I share something, none of the 3d models show up.
And when I open theirs, the same thing happens.
