OK, I'm probably getting my methodologies mixed up here!
We have a central library solution of code which is shared across Sitecore sites ... Inside of this, we have a Foundation project containing some Serialisation config files and binaries for Unicorn syncing.
We then have a standard Helix web site solution that will consume the central library solution as a NuGet package.
What we want is when the website solution is deployed (we are using Helix Publishing Pipeline but the approach shouldn't differ from Gulp/Cake scripting), the config files from the central library (nuget package) to also be deployed to the webroot.
Is this possible? What alternative ways of doing it are there?
