Hi!
When I try to build voxl-open-vins-server using voxl-cross:V4.4, first I run:
```
./install_build_deps.sh qrb5165 dev
```
After which I build and face this error:
```
voxl-cross(4.4):~(voxl-open-vins-server)(0.5.6)$ ./build.sh qrb5165
Found voxl-cross version: 4.4

Let me know how I can get past this, thanks!

Also experiencing this issue. @Eric-Katzfey could you provide any inside here? I've also tried different branches in the open vins server repo and different branches for install_deps such as staging and sdk_1.6

@Alex-Kushleyev any ideas?

@bendraper Yes, we can recreate the failure. We need to release voxl-cross 4.8. We're working on it.

@bendraper Actually, if you try to build the dev branch in voxl-cross:V4.4 it works but you first need to initialize the submodule with `git submodule update --init`. Can you try this with the dev branch and see if it works for you?

@Eric-Katzfey I got about a million warnings when actually building but it did appear to build after initializing the submodules. Thanks!

@bendraper 
Hello,
I hope this quick clarification helps for warnings:

CMake Policy warnings: OV internally (external dir in the repo) still uses boost and references an older cmake version -- **it's a harmless warning for devs** (as you are building from scratch)

Yaml-cpp lib warnings: This is a third party dependency that gets compiled from scratch during the make/build process. We use C++ 17 but the library is based on an older C++ version; nevertheless, it compiles fine on C++ 17 with minor warnings.  -- **it's a harmless warning** 

TrackOCL warning: ModalFlow is a core library written in C++ 17 that allows function call usage as done in TrackOCL, i.e., **the narrowing conversion is harmless in this case**.

That being said, we are actively working on the dev branch, so all flight--impacting warnings are hopefully caught early. We currently have no flight-impacting warnings/bugs identified, but if you found one warning/bug that caught your attention, please feel free to share. 

All the best,
ZBFT
