Need assistance resolving LNK1104: cannot open file 'opencv_core231.obj' when building an opencv helloworld with vs2010

I followed the guide at the link below in order to get a hello world source to compile but I keep getting a link error as shown in the title. I don't understand why. I did include the file "opencv_core231.lib" from the vc10 directory in the linker input section of my project properties (among other things directed in the guide). Any ideas?

You may have forgot the .lib in the Linker->Input->Additional Dependencies section. For example you have to write "opencv_core241d.lib" instead of "opencv_core241d"

In the 4-6 weeks I've been working with OpenCV 2.3 and Microsoft Visual Studio, I have copied all needed .dll files to my project folders. I believe that this is just how it is "done". I'm not saying you can't have some sort of link-sheet that you can import every time, but it has been working fine for me.

If you are interested, I used this guide for setup:

http://www.anlak.com/using-opencv-2-3-1-with-visual-studio-2010-tutorial/

This guy uses a property sheet to make projects, further along the path, easier to make. It's a decent walkthrough, with the exception that I could not find the property manager, which can be revealed through "View > Other Windows > Property Manager".

Hope this shed some light on your issue.
