So then I ran ./install_build_deps.sh apq8096 dev
and I get this:

Done installing dependencies

I assume both cases have issues, nevertheless, I tried running ./build.sh after both and in both cases the build fails. In both cases the output of ./build.sh indicated that various header files were not found. One common file was log/log.h. So I tried adding voxl-logger to DEPS_APQ8096 in install_build_deps.sh, but that didn't help.

Then...
Looking at voxl-logger, I saw it had several dependencies, and I just happened to attempt to build jpeg-turbo, but if you look at the build instructions the files are listed in the working directory, then the instructions say to execute ./install_build_deps.sh, but it doesn't even exist in the directory!

So, I'm having a few build issues. Right now I'd like to just get over the voxl-camera-server hump, and have since noticed that there is also an apq8096-camera-server repository. So an additional question would be: what is the difference between voxl-camera-server and apq8096-camera-server? I just want to build the code prior to browsing it just so I know I'm looking at working code.
