No luck, I got stuck installing Einstein.  FLTK installed no problem, but halfway through Matthias' clear directions:

allen at jetson:~/EinsteinNewt/NEWT64/Build$ cmake  ..
     CMake Error at CMakeLists.txt:5 (cmake_minimum_required):
       CMake 3.15 or higher is required.  You are running version 3.10.2

Oh, well, Newt64 is optional, move on to actual Einstein

And, no luck:

allen at jetson:~/EinsteinNewt/Einstein/_Build_/Makefiles$ cmake -DCMAKE_BUILD_TYPE=Release ../..
    CMake Error at CMakeLists.txt:10 (cmake_minimum_required):
      CMake 3.15 or higher is required.  You are running version 3.10.2

This is ubuntu 18.04 LTS, so I guess I need to move to 20.04?
