Operating system: Ubuntu20.04 (VirtualBox)  
Slicer version: latest version  
Expected behavior: make the project  
Actual behavior: make the project failure

git: git version 2.25.1  
cmake: cmake version 3.16.3

I created a new Ubuntu20.04 system in virtualbox. Downloaded the pre-requisites and made the project accroding to: [GNU/Linux systems — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/linux.html#any-distribution)

I am quite pointless about how to solve the error because of so many dependencies.  
This is the output from terminal: [ubuntu make slicer.txt - Google Drive](https://drive.google.com/file/d/1y3Khxtt8afd8uRKwjc61vx8_Caf9RFS1/view?usp=sharing)

Yes I didn’t change the default variables for Cmake. I was building release version and according to “common error” set git protocol=false

Yes. I tried but did not work.  
Btw I use make -jN -k to use more cpu. I don’t know is it the problem. I am trying to use just make to build it again.

I did a fresh build on ubuntu 20.04 and did not run into this error so it’s possibly something with your virtual box maybe running out of disk space or memory. I did `make -j20` on a 12 core machine. Try completely deleting your superbuild directory and starting from scratch in case there were any failed build files left behind by accident.
