"interface using qt" mean using (qt-based) ide (integrated development environment)?
if so, one? setting include list , *.h files think need find/work out add in linker directive -lwiringpi . depends upon ide you're using, afaik.**
trev.
** use ide's myself, having worked large, complex combined 'c' & (legacy) fortran program original makefiles not compatible "modern" ide's before retired. of later, 'c' software, built using autotools methods fine "anjuta" ide, but, w.r.t. pi, prefer use favourite editor , autotools build system.
