PART 1: Install a boatload of dependencies

sudo apt-get install extra-cmake-modules qtbase5-dev libqt5x11extras5-dev qtdeclarative5-dev libkf5coreaddons-dev libkf5i18n-dev libkf5globalaccel-dev libkf5config-dev libkf5xmlgui-dev libkf5widgetsaddons-dev libkf5windowsystem-dev libkf5notifications-dev libkf5dbusaddons-dev plasma-framework-dev kdoctools-dev libx11-dev


PART 2: Build and install the Wacom control panel

git clone git://anongit.kde.org/wacomtablet 
cd wacomtablet
mkdir build 
cd build 
cmake ../ -DCMAKE_INSTALL_PREFIX=/usr -DKDE_INSTALL_PLUGINDIR=/usr/lib/x86_64-linux-gnu/qt5/plugins
make -j8 
sudo make install 


Make sure the installation paths are correct.  
In particular, verify that .so files have been put in /usr/lib/x86_64-linux-gnu/qt5/plugins.  
I once had to run this command:
sudo cp -r /usr/lib/x86_64-linux-gnu/plugins/* /usr/lib/x86_64-linux-gnu/qt5/plugins 



START THE SERVICE:
kquitapp kded5 && kded5

Hi , thanks for the nice install instructions.
Sadly, this didn't work for me.

at Step:

make -j8

I got an error saying:

/home/kalikal/wacomtablet/src/common/tabletprofile.cpp:127:41: error: ‘qAsConst’ was not declared in this scope
     for (const auto &key : qAsConst(keys)) {

I tried updating Qt (qAsConst() function was introduced in Qt 5.7 https://github.com/maxrd2/subtitlecomposer/issues/88 ) with
sudo apt-get upgrade libqt4-dev
Sadly, this didn't solve the problem.
