@johnwason Any thoughts on why the windows build is finding a cache but seems to still build all of the vcpkgs? This does not happen on the tesseract build.

@Levi-Armstrong no, I don't see where the issues is. I don't know if it will cache a pull request, maybe that is the issue?

Is that what this line is doing?

No, that line prevents caching for release builds. I start my releases with v.
