I installed SDK 1.0.0 on a VOXL2 and during compiling of our own code I get the following error:

```
fatal error: voxl_vision_hub.h: No such file or directory
 #include <voxl_vision_hub.h>
          ^~~~~~~~~~~~~~~~~~~
compilation terminated.
```

I checked the folder `/usr/include/` and the file is missing over there:

```
voxl2:~$ ls /usr/include/voxl_*
/usr/include/voxl_common_config.h  /usr/include/voxl_imu_server.h  /usr/include/voxl_qvio_server.h                 /usr/include/voxl_vision_px4.h
/usr/include/voxl_cutils.h         /usr/include/voxl_io.h          /usr/include/voxl_slpi_uart_bridge_interface.h

/usr/include/voxl_io:
i2c.h  other.h  spi.h

/usr/include/voxl_trajectory:
setpoint_position.h  trajectory_evaluation.h  trajectory_interface.h  trajectory_protocol.h  trajectory_utils.h  voxl_trajectory.h
```

I believe this is caused because the new header file is not set as public header in this file: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/blob/master/src/CMakeLists.txt#L32

I would expect that when that is changed to
```
set_target_properties(voxl-vision-hub PROPERTIES PUBLIC_HEADER "../include/voxl_vision_px4.h;../include/voxl_vision_hub.h")
```
it will work.

Is that correct?

@Tjark 

Thanks for pointing this out! I applied your fix in voxl-vision-hub v1.6.7 which is now up on the staging repository and will be included in SDK 1.0.1

Best Regards,
