Support open3D in C++

[Sollimann]

Hey, again. I saw that you had added PCL without visualization (seems to be due to lack of vtk) and open3D in Python. Would it be possible to either add PCL with visualization, or open3D in C++? :) Preferably open3D in C++. So that you could optionally install open3D in C++ rather than in Python and vice versa :) Again, keep up the good work. Great initiative to create this repo!

Thanks for the suggestion!

You're right on the status on PCL - vtk source build seemed a bit complicated, so it's been delayed to v1.0. But there is a plan to support the full features of PCL 😸

I did not know there is a C++ API for Open3D. I'll definitely look into it!

I'll mark this issue as a todo-task for v1.0. Also I'll make a separate issue for PCL with visualization.
