cmake: Remove option for examples

The examples are now individual projects, which use Wakaama as external
dependency. There is no need anymore to enable the examples in the CMake
project.

 ## Examples
 
-The examples can be enabled (or disabled) with the CMake cache variable `WAKAAMA_ENABLE_EXAMPLES` (e.g.
-`cmake -DWAKAAMA_ENABLE_EXAMPLES=OFF`).
-
 There are some example applications provided to test the server, client and bootstrap capabilities of Wakaama.
 The following recipes assume you are on a unix like platform and you have cmake and make installed.
