Hi, I'm trying to build an updated voxl-qvio-server package with the last version available on dev brench. 
While following the build instructions on voxl-qvio-serer repo I run './build.sh apq8096', but after running I got the following error - 
"/home/root/server/main.cpp:46:10: fatal error: mvVISLAM.h: No such file or directory
 #include <mvVISLAM.h>
          ^~~~~~~~~~~~
"
After searching up for the file I realized there is not such file in the directory at all... I'm just trying to understand how should I be able to build the package without the required file...

@Yohai,

Are you building in the correct docker environment? voxl-qvio-server must be built within the voxl-emulator image, which has the necessary files baked in. 

From the README of the project:
```
prerequisite: voxl-emulator docker image >= v1.7 for APQ8096, qrb5165-emulator (>=1.3) for qrb5165 builds.
```

@Matt-Turi Ty, I used a different image(voxl cross image), it is working with the voxl emulator.
