I mentioned this in follow-up to a previous issue, but never got any reply, so I suspect no one noticed it. This is still happening, exactly as described below, with version 1.14.16.

One strange behavior remains. With 1.13.7, my output from above becomes:

[proc] Executing command: /home/mhellige/drw/test/../cpp-build-tools/gcc11.2.0-1 -v
... [ everything is fine, cmake runs ok, etc. then finally: ]
[proc] The command: gcc11.2 -v failed with error: Error: spawn gcc11.2 ENOENT
[proc] The command: g++11.2 -v failed with error: Error: spawn g++11.2 ENOENT

(And the stray directories are no longer created in my home dir.)

I still can't figure out those last two ENOENT lines... Where in the world is gcc11.2 coming from? My compiler binary is called gcc11.2.0-1, as you can see above. I can't find that string in any file in the workspace, nor in ~/.vscode or ~/.local/share/CMakeTools. I've tried enabling trace logging and everything else I can think of, but I can't for the life of me figure out where it's getting the string gcc11.2...

I'm not sure if this is a different bug, or a configuration issue, or what, but I would be very grateful for any insight!
