I am a beginner in OpenCV2.3 on Windows7 and Visual Studio2010 and finding a tough time(confused rather due to several version available in google) in installing the blob library. I am aware that there are several posts on SO itself dealing with this question. So, kindly bear with this question. These are the steps that I did. 
- Downloaded the library from Grossman's blob detection library
 - Extracted the zipped folder
 - Created a New Visual Studio 2010 blank project 
C:\Users\Admin\Documents\Visual Studio 2010\Projects\Blobafter reading Link1 - Copied the two .cpp files from Step(1) under 
Sourcefolder and copied the include.h underHeaderfolder in VS2010. Then, I included the Additional Libraries and Other Dependencies which we normally do to run any OpenCV program. - This is where I am lost >> Followed Link2. In my version of Cmake2.8.7 under Where is the source code I have 
C:/OpenCV2.3/opencv/opencvand under Where to build libraries, I haveC:/Users/Shreya/Downloads/OpenCV2.3. What should be done now? 
Would be highly grateful for a detailed explanation.
