Getting this linking error building any branch of voxl-portal or voxl-tflite-server: 

```
"/usr/lib/gcc-cross/aarch64-linux-gnu/7/../../../../aarch64-linux-gnu/bin/ld: warning: libwayland-server.so.0, needed by //usr/lib/libgbm.so, not found (try using -rpath or -rpath-link)
//usr/lib/libgbm.so: undefined reference to `wl_resource_get_user_data'

```

@teddy-zaremba Temporary fix by just installing missing package: 

```
apt-get install -y libwayland-server0:arm64 libwayland-dev:arm64
```

Also have to install this for voxl-portal
```
apt-get install -y libglib2.0-0:arm64
```
