Unknown command "ogre_config_sample_lib" when cmake samples of OGRE

An error of Unknown CMake command "ogre_config_sample_lib" happens when I tried to use cmake in OGRE Sample folders after installing OGRE. I had taken the following steps before this error happened:

cd to the folder Sample/Smoke, and mkdir a new directory named build and cd there. Run cmake .. after that and meet the error then.

Here's the detail information of my error:

tibur is correct in that you are not supposed to run cmake from there. Do what you did, but in the root of the SDK dir.

You probably not supposed to run CMake from that directory. Try to run it for the whole Sample directory. If it doesn't work either, check where that ogre_config_sample_lib command is defined.

In the root ogre directory there is .bat file that will compile the samples for you. I also tried doing cmake from src and other directories and got the same error, but the .bat file compiled all the samples for me easily.
