Build on Ubuntu 18.04 with DBUS and other custom cmake configuration options fails

[bonedaddy]

Describe the bug Attempting to build ethminer with the -DETHDBUS=ON cmake flag fails due to the following error

In file included from /home/rtrade/ethminer/ethminer/main.cpp:22:0:

To Reproduce Install ubuntu 18.04 desktop, and install nvidia with the following script

#! /bin/bash

# This installation method requires at least one GPU being plugged into the system
# before you run this script so that we may utilize the ubuntu-drivers utility
# to install the recommended version for each rig.

DISTRO=$(lsb_release -sc)
if [[ "$DISTRO" != "bionic" ]]; then
    echo "[ERROR] Installation only supported for 18.04"
    exit 1
fi

Then build ethminer with the following script

Omitting the -DETHDBUS=ON flag got me a little further, however I'm not getting a new error:

Omitting everything and just goign with the default using cmake .. caused no problems and I was to successfully build ethminer

[jean-m-cyr]

Fixed
