What steps will reproduce the problem?
1.already done everything on muct.
2.cmake
3.

What is the expected output? What do you see instead?
according to the guide, nothing should be modified to configure with cmake. 
However I saw this.

What version of the product are you using? On what operating system?
The latest version. Ubuntu 12.04 64-bit.

Please provide any additional information below.
I think this is because I have already installed opencv but what should I do?
