+## Using cmake template macros
+
+To leverage all cmake templates features, you have to specify ***properties***
+on your targets. Some macros will not works without specifying which is the
+target type.
+
+As the type is not always specified for some custom targets, like an ***HTML5***
+application, macros make the difference using ***LABELS*** property.
+
+Choose between:
+
+- **BINDING**: Shared library that be loaded by the AGL Application Framework
+- **BINDINGV2**: Shared library that be loaded by the AGL Application Framework
+ This has to be accompagnied with a JSON file named like the
+ *${OUTPUT_NAME}-apidef* of the target that describe the API with OpenAPI
+ syntax (e.g: *mybinding-apidef*).
+ Or Alternatively, you can choose the name, without the extension, using macro
+ **set_openapi_filename**. If you use C++, you have to set **PROJECT_LANGUAGES**
+ to *CXX*.
+- **BINDINGV3**: Shared library that be loaded by the AGL Application Framework
+ This has to be accompagnied with a JSON file named like the
+ *${OUTPUT_NAME}-apidef* of the target that describe the API with OpenAPI
+ syntax (e.g: *mybinding-apidef*).
+ Or Alternatively, you can choose the name, without the extension, using macro
+ **set_openapi_filename**. If you use C++, you have to set **PROJECT_LANGUAGES**
+ to *CXX*.
+- **PLUGIN**: Shared library are meant to be used as a binding plugin. A 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.
+- **BINDING-CONFIG**: Any files used as configuration by your binding.
+
+Optional **LABELS** are available to define which resources type your test
+materials are:
+
+- **TEST-CONFIG**: JSON configuration files that will be used by the afb-test
+ binding to know how to execute tests.
+- **TEST-DATA**: Resources used to test your binding. It is at least your test
+ plan and also could be fixtures and any files needed by your tests. These files
+ will appear in a separate test widget.
+- **TEST-PLUGIN**: Shared library meant to be used as a binding
+ plugin. Binding would load it as a plugin to extend its functionalities. It
+ should be named with a special extension that you choose with SUFFIX cmake
+ target property or it'd be **.ctlso** by default.
+- **TEST-HTDOCS**: Root directory of a web app. This target has to build its
+ directory and put its files in the ${CMAKE_CURRENT_BINARY_DIR}/${TARGET_NAME}
+- **TEST-EXECUTABLE**: Entry point of your application executed by the AGL
+ Application Framework
+- **TEST-LIBRARY**: An external 3rd party library bundled with the binding for its
+ own use in case the platform doesn't provide it.
+
+Here is a mapping between LABELS and directories where files will be placed in
+the widget:
+
+- **EXECUTABLE** : \<wgtrootdir\>/bin
+- **BINDING-CONFIG** : \<wgtrootdir\>/etc
+- **BINDING** | **BINDINGV2** | **BINDINGV3** | **LIBRARY** : \<wgtrootdir\>/lib
+- **PLUGIN** : \<wgtrootdir\>/lib/plugins
+- **HTDOCS** : \<wgtrootdir\>/htdocs
+- **BINDING-DATA** : \<wgtrootdir\>/var
+- **DATA** : \<wgtrootdir\>/var
+
+And about test dedicated **LABELS**:
+
+- **TEST-EXECUTABLE** : \<wgtrootdir\>/bin
+- **TEST-CONFIG** : \<TESTwgtrootdir\>/etc
+- **TEST-PLUGIN** : \<wgtrootdir\>/lib/plugins
+- **TEST-HTDOCS** : \<wgtrootdir\>/htdocs
+- **TEST-DATA** : \<TESTwgtrootdir\>/var
+
+> **TIP** you should use the prefix _afb-_ with your **BINDING* targets which
+> stand for **Application Framework Binding**.
