{python3packages.py,}meshlab: 2023.12 -> 2025.07 + use system dependencies , and update dependencies #445078

nim65s · 2025-09-21T21:59:39Z

Hi,

This PR update meshlab & python3Packages.pymeshlab from 2023.12 to 2025.07, among other things to fix build with CMake v4.

It also update their dependencies (levmar, lib3mf, tinygltf, vcg, corto, and nexus) and their packaging to use standard CMake exports (ref. cnr-isti-vclab/vcglib#248)

While here, meshlab-unstable is dropped, since it was older than 2025.07, cc. @pca006132

When I started to work on this, I did not see the work from #396295 (merged only 4 days ago), so I tried to merge this work with mine, but a few things might seem odd in the history. cc. @yzx9

I tested that by opening meshlab GUI and loading a mesh (only on linux) and trying a simple mesh decimation from python (linux & darwin):

$ nix-shell -I nixpkgs=. -p 'python3.withPackages(p: [p.pymeshlab])' --command python
>>> from pymeshlab import MeshSet
>>> ms = MeshSet()
>>> ms.load_new_mesh("/…/base_link.STL")
>>> ms.meshing_decimation_quadric_edge_collapse()
>>> ms.save_current_mesh("/…/base_link2.STL")

And, yes, base_link2.STL takes less disk space than base_link.STL (a random file from example-robot-data)

Things done

qt applications on drawin include a sandbox profile, so they don't work with sandbox = true

And I suspect lib3mf run into OOM error based on the log
