How to add gems folder to allinoneruby exe?

Hello, I’m building an exe with allinoneruby, but how do i add the gems
folder C:\ruby\lib\ruby\gems ? I tried to change the sitedirlib by
editing rbconfig.rb, then I tried to use the -s with allinoneruby to
include my site_ruby folder, thinking it would include my gems folder
and
all subfolders, but my libraries still can’t load. suggestions?
