Windows actions suddenly fail needing a .nuspec file

After my most recent commit I noticed both my windows runners have failed while running the “CPACK” step. With the error
No .nuspec files (or more than 1) were found to build in 'D:\a\blackchocobo\blackchocobo'. Please specify the .nuspec file or try in a different directory. The commit in question is small update for MacOS Rpath stuff, in a cmake file inside an if(APPLE) block.

What has caused me to suddenly need a .nuspec file (or have to0 many). I do not generate any or use nuget packages in the action.
