OpenSceneGraph LNK2019

我正在尝试使用OpenSceneGraph。我已经使用CMake和Visual Studio 2013 X64来编译源代码。现在，我想建立一个项目，但是出现以下错误：

Error   1   error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl osgViewer::Viewer::Viewer(void)" (__imp_??0Viewer@osgViewer@@QEAA@XZ) referenced in function main  C:\Users\epsilon-pc\documents\visual studio 2013\Projects\osgtest2\osgtest2\mainApp.obj osgtest2

我已经添加了VC / C ++附加包含和链接器附加库目录和输入

osgGAd.lib;
osgFXd.lib;
osgUtild.lib;
osgd.lib;
osgDBd.lib;

这是我的代码（很简单）：

#include <osgDB/ReadFile>
#include <osgViewer/Viewer>

int main(int argc, char** argv)
{
    osgViewer::Viewer viewer;
    viewer.setSceneData(osgDB::readNodeFile("cessna.osg"));
    return viewer.run();
}
