i have made qt gui in ros, kinetic environment.

then i would use the qcustomplot.

but, it generated error

that is
"
Error: NOTIFY signal 'layerChanged' of property 'layer' does not exist in class QCPLayerable.
ceres_gui/CMakeFiles/ceres_gui.dir/build.make:72: recipe for target 'ceres_gui/include/ceres_gui/moc_qcustomplot.cxx' failed
"

I want to know how to resolve that.
