Build the game by executing `docker build -t zerohour .`

After the build you can run the container and use `docker cp`
or you could mount a volume to `/build` so you can directly

```bash
# 1. Start the container in the background
docker run -d --name zh_builder zerohour

# 2. Copy the executable to your host machine
docker cp zh_builder:/build/cnc/build/vc6/GeneralsMD .
```

Or you could mount a volume to `/build` so you can directly
compile your own code and copy the binary off.
