Error compiling CFDEM coupling

Dear all,

I am trying to compile CFDEMcoupling on Ubuntu 18.04 hosted on wsl. I am following the instructions here: https://www.cfdem.com/media/CFDEM/docu/CFDEMcoupling_Manual.html#install...

When I run cfdemCompCFDEMall, LIGGGHTS seems to be compiling fine, but the installation of CFDEM is failing.
I am attaching the output of the terminal. There are a lot of lines starting with "could not open file ". I have seen that this might not be a problem, but in my case the tutorials are not working. Seems to me the executables are not compiled.

Also, here is the output of cfdemSysTest
