C++ library import with problem when adding the osg and the osgearth lib

Question

I try to add the osg and the osgearth lib to my Qt project.After qmake I try to build the whole project but something is wrong.Here are the errors and my .pro file

I have tried clear the whole project and qmake again,then rebuild the project,but it didn't work. What I expect is that the osg lib imported successfully and the project has built correctly.
