The easy way to get it working:

copy QPPlot*.* to a qt or kde project
copy also the generic files ../PPlot.* to your qt or kde project
make sure the new files will be built
add somewhere the QPPlotExample widget.

A better way (for unix like systems):

link QPPlot*.* to a qt or kde project
build a library pplot.a from generic code in ../
Add "locationof/PPlot.h" to the include path
Add "pplot.a" to link libraries


Beware of the GPL license. (Something you have to live with anyway if you are using qt)
