includePath support for non-local paths ssh:// in particular

Please review existing issues and our documentation at https://github.com/Microsoft/vscode-cpptools/tree/master/Documentation prior to filing an issue.

Describe the bug

• OS and Version: Windows 7 Enterprise
• VS Code Version: 1.25.1
• C/C++ Extension Version: 0.17.6
• Other extensions you installed (and if the issue persists after disabling them): SSH FS 1.9.2

IntelliSense fails to parse files provided by extensions that implement FileSystemProvider. In my case: SSH-FS SchoofsKelvin/vscode-sshfs#27

To Reproduce

1. install vscode-cpptools
2. install vscode-sshfs
3. configure a remote directory in user settings
4. configure c_cpp_properties.js includePath to use the ssh FileSystemProvider

Expected behavior
IntelliSense should work as it does for local files

User Settings:

        {
            "name": "home",
            "label": "jwieber",

We currently don't support URI syntax in the includePath nor any scheme besides file:// right now. Marking as a feature request.

[jdwieber]

Hello. I see in version 1.26 of VS Code that we can now open an URI as a folder. Does that bring us any closer to this being supported in cpptools? Thanks.

[bobbrow]

I'm sorry, at this time we don't have an ETA as to when this issue will be addressed.

[aosterthun]

Has something changed about this feature ?

[sean-mcmanus]

@aosterthun Nothing has changed. We should work with the various VS Code remote extensions that create a remote extension instance (i.e. use file:// instead of ssh://).

[github-actions]

This feature request has received enough votes to be added to our backlog.

This would be nice to have, as sshfs is a work-around to microsoft/vscode-remote-release#401
for us ppc64le users :(

using vscode without IntelliSense kind of eliminates the point.
