/*
Note that this version of the extension still has some nix specific issues
which could not be fixed merely by patching (inside a C# dll).
In particular, the debugger requires either gnome-terminal or xterm. However
instead of looking for the terminal executable in `PATH`, for any linux platform
the dll uses an hardcoded path to one of these.
So, in order for debugging to work properly, you merely need to create symlinks
to one of these terminals at the appropriate location.
The good news is the the utility library is open source and with some effort
we could build a patched version ourselves. See:
<https://github.com/Microsoft/MIEngine/blob/2885386dc7f35e0f1e44827269341e786361f28e/src/MICore/TerminalLauncher.cs#L156>
Also, the extension should eventually no longer require an external terminal. See:
<https://github.com/Microsoft/vscode-cpptools/issues/35>
Once the symbolic link temporary solution taken, everything shoud run smootly.
