Subject: [bug#78414] [PATCH] gnu: openscad: Fix python support
Date: Wed, 14 May 2025 02:16:47 +0200

* gnu/packages/engineering.scm (emacs-scad-mode): Add missing nettle input; add patch for CMake to fail build if nettle isn't found

Change-Id: Ic6bea14048daac56dc8773bf8fbdbd3bb1f0eae9
---
Python support requires Nettle as an input which is nowhere documented.
Also due to a bug in the CMake scripts, the build process doesn't fail if
CMake is missing but just disables Python support in that case.

I've filed an upsrtream bug report and pull request for fixing CMake,
added a temporary patch to the packet until the PR is merged
and added the missing Nettle input.
