don't do that in Debian :-)

in Debian we let update-alternatives do all the hard works for us :-)
sudo update-alternatives --install /usr/lib/libqwt.so libqwt.so
/usr/lib/libqwt-qt4.so 1

Also you would need:

sudo update-alternatives --install /usr/include/qwt qwt /usr/include/qwt-qt4 1

and then you can remove it later with an update-alternatives --remove.
 More info is available in the update-alternatives man page :-)
