ArtifexSoftware.GhostScript is no longer available #26
Description
Pull-request microsoft/winget-pkgs#122306 removed one of the requirements to be installed using winget. As is described in microsoft/winget-pkgs#122294 it is not possible to re-add it.
It seems @ArtifexSoftware has unpublished the blog post referenced. They have also killed the possibility to clone their repo. The webinterface is still viewable at https://cgit.ghostscript.com/cgi-bin/cgit.cgi/ghostpdl.git, but that's quite pointless.
% git clone https://cgit.ghostscript.com/cgit/ghostpdl.git
Cloning into 'ghostpdl'...
fatal: repository 'https://cgit.ghostscript.com/cgit/ghostpdl.git/' not found
Lua itself should have no other requirements than a C compiler.
How important is ghostscript to build Lua and how does it work? I see no direct use of neither gs or ghostscript in CMakeLists.txt, but guess it is an indirect dependency when using ImageMagick to convert the postscript into an icon.
Could we perhaps check in the generated icon and remove both GhostScript and ImageMagick from the dependencies?
