+Building locally on rPi
+=======================
+

+2) Run "make install" (replaces /home/pi/runCamera)
+3) Run "./runInteractive" in /home/pi or "sudo svc -t /service/camera" to

+/usr/local/frc/lib and /usr/local/frc/include to the local desktop locations.
+
+Building
+--------
+
+1) Run "make CXX=arm-raspbian9-linux-gnueabihf-g++"
