Debs have a path precedence over the snaps, so, if the cmake snap is shipped with the cmake, the cmake deb is used by default until the `PATH` is overriden, which is problematic. see [here](https://invent.kde.org/network/neochat/-/merge_requests/2055) --- - [x] Have you signed the [CLA](http://www.ubuntu.com/legal/contributors/)?
