The Qt documentation explains all options in detail:

• http://qt-project.org/doc/qt-5.0/qtdoc/deployment-plugins.html

cp ../qwt-6.1.2/plugins/designer/libqwt_designer_plugin.so ../QtCreator/bin/plugins/designer/
cp ../qwt-6.1.2/lib/* ../QtCreator/lib/qtcreator/
cp ../qwt-6.1.2/lib/* ../QT5.5/gcc_64/lib/
