Cmake can't find OpenCV

[GoogleCodeExporter]

What steps will reproduce the problem?
1. cd /tmp && wget 
http://pam-face-authentication.googlecode.com/files/pam-face-   
authentication-0.3.tar.gz

2. tar zxf pam-face-authentication-0.3.tar.gz && cd pam-face-authentication-*

3. mkdir build && cd build

4. cmake -D CMAKE_INSTALL_PREFIX=/usr ..

5. make

6. sudo checkinstall --pkgname=pam-authentication-face-auth 

What is the expected output? What do you see instead?

After doing cmake -D CMAKE_INSTALL_PREFIX=/usr ..
i get this output

This looks like a duplicate of issue #75
