-- **BINDINGV2**: Shared library that be loaded by the AGL Application Framework.
- This has to be accompagnied with a JSON file named like the *${OUTPUT_NAME}-apidef* of
- the target that describe the API with OpenAPI syntax (e.g: *mybinding-apidef*).
- Or you can choose the name by setting the *CACHE* cmake variable *OPENAPI_DEF*
- (***CAUTION***: setting a CACHE variable is needed, or set a normal variable
- with the *PARENT_SCOPE* option to make it visible for the parent scope
- where the target is defined) JSON file will be used to generate header file
- using `afb-genskel` tool.

+ This has to be accompagnied with a JSON file named like the

+ extension, by setting the *CACHE* cmake variable *OPENAPI_DEF* (***CAUTION***:

+- **PLUGIN**: Shared library meant to be used as a binding plugin. Binding
+ would load it as a plugin to extend its functionnalities. It should be named
+ with a special extension that you choose with SUFFIX cmake target property or
+ it'd be **.ctlso** by default.
 - **HTDOCS**: Root directory of a web app. This target has to build its
  directory and puts its files in the ${CMAKE_CURRENT_BINARY_DIR}/${TARGET_NAME}
 - **DATA**: Resources used by your application. This target has to build its
  directory and puts its files in the ${CMAKE_CURRENT_BINARY_DIR}/${TARGET_NAME}
 - **EXECUTABLE**: Entry point of your application executed by the AGL
  Application Framework
+- **LIBRARY**: An external 3rd party library bundled with the binding for its
+ own purpose because platform doesn't provide it.
 
 > **TIP** you should use the prefix _afb-_ with your **BINDING* targets which
 > stand for **Application Framework Binding**.
