Command not found: build_octree

[MrGitGo]

I have troubles to install the viewer. Everything was fine until I had to run this command: target/release/build_octree When I run this I get this output: `error: The following required arguments were not provided:

--output_directory <output_directory

USAGE:
build_octree --output_directory <output_directory> --resolution `

and then I type this but without success: build_octree /home/nvidia/Documents/bagfiles2/bagfile.bag_points.pcd --output_directory /home/nvidia/Documents/output

Then I get this: zsh: command not found: build_octree

While I'm doing this I'm in ~/point_cloud_viewer

EDIT:
And when I try to install the sdl I get also errors with this command: cargo build --release

But I also could not install the sdl2 with the command cargo install sdl2

seems like you are fighting with your shell... Not something I can really help with.

Also the PCD file is not supported, you'll need a supported PLY file.

You did also not run through the README.md, likely missing a lot of the dependencies (like go and protobuf and sdl2). Best start there?
