I have imported the `Statistics.mean` function in my package and declared new methods for it. The code is fine and works well. I have documented the methods. While building the doc, Documenter gives me two Warnings and one Error:

┌ Warning: no doc found for reference ‘`missing`’ in src\riemannianGeometry.md.  
└ @ Documenter.CrossReferences C:\Users\congedom.julia\packages\Documenter\G5Sup\src\CrossReferences.jl:160  
┌ Warning: no doc found for reference ‘`skipmissing`’ in src\riemannianGeometry.md.  
└ @ Documenter.CrossReferences C:\Users\congedom.julia\packages\Documenter\G5Sup\src\CrossReferences.jl:160  
[ Info: CheckDocument: running document checks.  
ERROR: SystemError: opening file “C:\cygwin\home\Administrator\buildbot\worker\package\_win64\build\usr\share\julia\stdlib\v1.1\Statistics\src\Statistics.jl”: No such file or directory

I am working on Windows 10 with Julia Version 1.1.0.  
I have installed cygwin, but that did not solve the error.

P.S. this seems related to [19414](https://discourse.julialang.org/t/error-loaderror-ioerror-chdir-buildworker-worker-package-linux64-build-usr-share-julia-stdlib-v1-0-sockets-src-no-such-file-or-directory-enoent/), but the discussion did not end there.
