I downloaded conky from github: <https://github.com/brndnmtthws/conky>

then I installed it using this method:

```
$ mkdir build
$ cd build
$ ccmake /home/user/conky
# this will launch a curses-based UI where you can configure
# everything, when you are ready you can build as usual:
$ sudo make  # This will compile conky in the `src` subdirectory
$ sudo make install

```

then I wanted to uninstall it; I deleted the directories /build and /conky

and I did `sudo apt-get --purge remove conky conky-all`

then I rebooted, but conky still starts.

How do I delete conky?
