This command is unfortunately still in development. In an initial experimental setup, I've linked to some MATLAB code for parts of it, e.g., the [Hungarian algorithm](https://github.com/BioMedIA/MIRTK/blob/9473b875d88413f3f6f8cec5e213c3ced82f3c2f/Modules/PointSet/src/SpectralDecomposition.cc#L297) and the Coherent Point...

Not yet. But I don't see what's the difference to having it downloaded via `git submodule`.

Well, it's not that I would not like to add it. It has always been on the TODO list. There is some basics in there, but not complete. Also, ExternalProject...

For the purpose of the ThirdParty libs in MIRTK, I think it is sufficient to simply perform the download step by running "git clone" or CMake's `file(DOWNLOAD)` command during CMake...
