[O] pdf files with openwith only, and only this.

[Joseph Vidal-Rosset]

Hi the list,

I do not want to use pdf-tools to view pdf in emacs, I want only to
use an external program (evince) to view pdf files. Unfortunately,
links to pdf do not work with openwith and my emacs open on a pdf. I
cannot delete pdft-tools that is a dependency of org-ref that I am
using. A solution for my setup would be welcome.

Best wishes,

Jo.
