opencv - how do you build an open CV c/C++ file using Cmake exactly?

Question

I have attempted to build the "kmeans.cpp" or "kmeans.c" file using gcc/g++ however I'm getting a lot of undefined references to opencv libraries, although I have installed Open CV successfully.

Can someone guide me how to build a simple C/C++ file using CMake?

Do I just do "cmake kmeans.cpp"?

I'm on OS X 10.6.8.
