Comment:
I'm getting build errors while cross compiling. Could you look into them, please?

```
/bin/sh: /bin/sh: /usr/armv7l-linux-musleabihf/usr/bin/fluid: cannot execute binary file: Exec format error/usr/armv7l-linux-musleabihf/usr/bin/fluid: cannot execute binary file: Exec format error
```

You might need `fltk` in `hostmakedepends`
