Additional dependencies for Ubuntu

[rdrms]

Had to install the following to get it to run. Also for some reason (Ubuntu 19.10) gmake didn't exist, which is normally a symlink to make. It was complaining gmake was useless, so I made a symlink in /usr/bin/ from make to gmake which satisfied it.

These are the additional packages I ended up installing on Ubuntu 19.10:

cmake
kwin-dev
qttools5-dev
libkf5crash-dev
libkf5notifications-dev
libkf5kio-dev
kinit-dev
libkf5package-dev

so the line should be:

sudo apt install build-essential libkf5config-dev libkdecorations2-dev libqt5x11extras5-dev qtdeclarative5-dev extra-cmake-modules libkf5guiaddons-dev libkf5configwidgets-dev kwin-dev kwin-dev qttools5-dev libkf5crash-dev libkf5notifications-dev libkf5kio-dev kinit-dev libkf5package-dev cmake

Note that I reinstalled and this time gmake didn't give me any issues.
