There is a new pull request by Phicem against master on the void-packages repository

https://github.com/Phicem/void-packages CalculiX-2.20
https://github.com/void-linux/void-packages/pull/39984

CalculiX-2.20
### NEW PACKAGE - CalculiX

This new package conforms to the [package requirements](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#package-requirements): **YES**

CalculiX is a 3D finite element program. It is an optional but important dependency of FreeCAD (for mechanical and thermal calculations).

CalculiX is split in two parts: the solver (CalculiX-ccx) and the graphical interface and pre/post-processing (CalculiX-cgx).

This PR includes 5 packages, each in a separate commit:
- SPOOLES (build dependency for CalculiX-ccx)
- CalculiX-ccx
- tetgen (runtime dependency for CalculiX-cgx)
- CalculiX-cgx
- CalculiX meta-package (which brings CalculiX-ccx and CalculiX-cgx)


### Tests
#### Local build testing
- Native x86_64 (glibc): **OK**
- Native armv7l (glibc): **OK**
- Native *-musl: **NOT TESTED**

#### Cross build testing (from x86_64 machine)
- Cross-compiling to i686: **OK**
- Cross-compiling to *-musl: **FAILED** (package building has been disabled for musl architectures in the template file of this PR, until someone is able to test building on native musl architecture)
- Cross-compiling to armv7l / armv6l: **FAILED** (building works when compiling natively so it's probably not a big issue)

#### Runtime testing
- On x86_64: **OK** (for CalculiX-ccx: some calculation tests differ from the official reference results files)
- On armv7l: **OK** (for CalculiX-ccx: only basic tests have been run)
- On i686: **NOT TESTED**
