The projects are out of date!! (Visual Studio 2010 Express+OpenCV 2.4.0)

edit

When I want to debug the *.sln fine (generated by Cmake) in Visual Studio 2010, I come accross this problem:

The projects are out of date :

ZERO_CHECK - Debug Win32 zlib - Debug Win32 opencv_core - Debug Win32 libjasper - Debug Win32 opencv_imgproc - Debug Win32 libtiff - Debug Win32 libpng - Debug Win32 libjpeg - Debug Win32 opencv_flann - Debug Win32 opencv_highgui - Debug Win32

Would you like to build them?

After clicking "Yes".... the are the error with that:

'....\lib\Debug\opencv_gpu240d.lib' 6>LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_gpu240d.lib' 5>LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_gpu240d.lib' 4>LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_gpu240d.lib' 7>LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_gpu240d.lib' 8>LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_gpu240d.lib'
