Build issues

[Cepheides]

I am running on Ubuntu 18.04. I am trying to install Delphes by following the Quick Tour and I am trying to build Delphes with the command

make -j 4

However, when I run this command, here is my output:

>> Building libDelphesNoFastJet.so

The fix is in the new release (3.5.0).
