Reroute all files in `source/static/` to `build/` during build

I have static files in my source/static/ directory. I want Middleman to copy them verbatim to the build directory.

It does copy them verbatim, but it prepends static/ to the URL. I don’t think it’s valuable/important for the site visitor to know the files were built in a static manner.

I’ve tried searching for middleman routes etc, but haven’t found any way to do this.

I also tried putting the contents of source/static/ directly in source/ but Middleman seems to ignore them during the build phase.

TL;DR: How do I make files in middleman-site/source/static/abc be copied verbatim during build phase to middleman-site/build/abc ?

Ignore them during build, and then move them to wherever you want them using after_build.
