How to debug an external library (OpenCV) in Visual C++?

Question

I am developing a project in VC++2008. The project uses the OpenCV library (but I guess this applies to any other library). I am working with the Debug configuration, the li

To sum up all the activity in the comments: the key to the solution was to rebuild the library in VC++ to obtain the .pdb (Program Debug Database) files for debugging, the precompiled "-d" suffix libraries weren't enough. Still, the import libs for the library dlls made the program load precompiled dlls from the OpenCV package tree, not the ones from my build with the .pdb information (the paths were similar so I didn't notice at first). The path to the .pdb files was provided in Tools|Options, but these files weren't loaded because of module version mismatch (obviously). Once I copied the correct dlls and their respective .pdb files to the application directory, the debugger started working inside the library functions.
