nongnu: Add uvtools.
- gnu/packages/cad.scm (uvtools): New variable.
This adds tool for manipulation of 3D files to be manufactured on resin printers.
It's opensource project, but in C# and therefore depends on MS build tools.
I've tried to build it using xbuild
from Mono, but it generated a lot of errors and wanted the MS toolchain instead.
Therefore it's taken as Appimage and just extracted and patched.
I tried to replace the dlls in the appimage with those from mono
package but then I got this error:
Failed to create CoreCLR, HRESULT: 0x80004005
Therefore to make this opensource package work it has to be used currently as AppImage.
