This “-any-any.yak” if I use yak as suggested here. So, I extracted the yak.exe and DLLs from the Rhino8 system folder into a separate folder, and I have the any-any result, but if I run the yak.exe in the Rhino8 system folder, I have the rh8_13-any result.
I can also get the rh8_13-any if I use the downloadable version.
Based on your suggestions, this seems to be the best solution for now.
Downloadable yak.exe.
Build a multi-target package for Rh8, then build a package for Rh7. The final result will be.
“blabla-0.0.1-rh8_13-any.yak” and “blabla-0.0.1-rh7_32-any.yak” .
