LINK : fatal error LNK1104: cannot open file '..\lib\Debug\cvblob.lib'

I got the same error in visual studio 2010. The problem is that visual studio 
does not create a lib file unless functions are explicitly defined as dllexport 
functions.
To fix this add the following to cvblob.h:

#define EXPORT __declspec (dllexport)

In the extern "C" block, add the word EXPORT to each function.
For example: 
EXPORT double cvContourPolygonArea(CvContourPolygon const *p);

As soon as you add at least one EXPORT keyword the .lib file will be created. 
You should add EXPORT to all the functions in the extern "C" block though, 
otherwise you will get linkage errors for the functions you didn't add EXPORT 
for.

This fix was based on the following MSDN post:
