Symbolic links in config path don't work

I reached a bug in Natron that seems to be related to OCIO: https://github.com/MrKepzie/Natron/issues/1719

This:
```
C:\app\inria\natron
```
Is a symlink to:
```
\\srvapp\app\inria\natron
```
`OCIO` env var is:
```
C:\app\inria\natron\2.3.4\Resources\OpenColorIO-Configs\blender\config.ocio
```
And it looks like `OCIO` can't reach the path because it's a Windows symbolic links to UNC paths:


1) Are we sure OCIO read the path `C:\app\inria\natron\2.3.4\Resources\OpenColorIO-Configs\blender\config.ocio` properly?
2) Would it be a Natron problem?

Thanks in advance! :)

Start by reproducing the OCIO environment-variable path using the Windows symbolic link from C:\app\inria\natron to the UNC path \\srvapp\app\inria\natron, and review the linked Natron issue #1719. The issue names no source file or test and does not define whether the fix belongs in OpenColorIO or Natron, so completion criteria need clarification.
