This folder contains a set of external libraries that are used in Open3D.

We want to make Open3D self-contained and cross-platform consistent. So
Open3D does not detect system installed libraries and always links to these
external libraries.

Some external libraries rely on basic system level libraries such as OpenGL and
libusb. Run corresponding script file under "script" directory to automatically
config them.
