Issue Description

After downloading the source for the python wrapper and compiling:

$ python -c "import pyrealsense2"
ImportError: /usr/local/lib/librealsense2.so.2.28: undefined symbol: __atomic_fetch_add_8

The fix was to add a -latomic to the gcc command creating librealsense2.so.2.28 so ldconfig knew it depended on libatomic. Could you consider adding the fix please?
