* gnu/packages/maths.scm (opencascade-7.6.1): New variable.
Change-Id: I24a4df83c77f62707ceff88ee1880d859c2bb2b5
---
prusa-slicer reverted back to version 7.6.1 of opencascade-occt as a hard-coded dependency
"because newer versions are triangulating chamfers incorrectly.".
See https://github.com/prusa3d/PrusaSlicer/commit/c6a02106fd1d3caa9a48a6b7c2bdd04546b24485.
This patch adds that version, so prusa-slicer could be built successfully.
