Cannot download the whole folder about labstreaminglayer

This is because most subfolders are linked to submodules, and git does not download them by default.

Try git clone --recursive or another of the many options git offers: https://stackoverflow.com/questions/3796927/how-to-git-clone-including-submodules

Does the program work too if I clone only a selected folder eg, Audio folder ?

Yes, but I doubt what I mean by "work" is the same as what you mean by "work". What I mean is that you can clone only an application repository and build the application, but you still need build tools, all of the application's dependencies, and to configure the build using CMake.

I think you may simply want to download the release from the GitHub repository Releases page. If there are no releases for your platform then please create an issue in the corresponding repository.
