how to install pybind11 on Ubuntu 18.04

[HamishB]

Hi,

more of an FYI for the install pages than a bug, but for anyone else who needs to get it going, Ubuntu 18.04 LTS comes with Pybind11 version 2.0.1 and the SM build fails as it needs version 2.5 or newer. Simply downloading the two .deb packages* for Ubuntu 20.10 (Groovy) and installing them over the top of the 2.0.1 version with dpkg works great.

[*] python3-pybind11 and pybind11-dev

Yes, the installation requirements are listed here.

It requires pybind11 >= 2.5 and CGAL >= 5.0 otherwise it cannot compile the CPP codes.
