When trying to build the project, I get the following error:

I've run into the same problem, but I have been able to compile successfully using an older version of cmake. I downloaded version 3.10.2 from the cmake website and installed it in my home folder. E.G. /home/linuxuser/bin/.

Adjust your $PATH variable to see your home bin folder first export PATH=/home/username/bin:$PATH and then run cmake --version to make sure you're using the correct version. If it shows you 3.10.2 you should be good to configure and compile.
