Undefined Reference to NetworkTable functions TX1

Hi CD,

I just got a working vision tracking code on the Jetson TX1 (watch out for ResetVision) and then I realized the network tables do not work. I used gradlew arm build to build it and am using CMake to compile projects. The first problem I got was it could not find NetworkTable.h (it found ntcore.h and wouldn’t work without both of them). I then moved the ntcore folder to my jetson code folder. The include problem went away but anytime I do a network table thing I get undefined reference to: NetworkTable::SetClientMode;

I have searched through other threads telling me to target link the build folder of ntcore but I do not have one.
