I made some changes. WPScore becomes a library.
But I have no idea of WPSlur. It seems that we must write all the functions defined in WPModifier(?).
Just FYI, to compile a plugin, use the command:
g++ WPSlur.cpp -o  libWPSlur.so -fPIC -shared -I /usr/include/qt5/QtCore -I /usr/include/qt5/QtMultimedia -I /usr/include/qt5 -I ./.. -I ./../include -L ./../lib -lWPScore -g
Good!
