+from your `app-templates` submodule path `app-templates/../cmake/`. + +**NOTE:** If the **ID_LIKE** field does not exist, you can use the +**ID** field. + +Files that you add must be named according to the following file naming +convention: + +- `XX-${OSRELEASE}*.cmake` + +In the naming convention, `XX` represents numbers and is the order in which +you want a file included. +The ${OSRELEASE} value is taken from either the **ID_LIKE** or **ID** field +of the `/etc/os-release` file. + +You can also configure a CMake file to be included in cases where no +specific operating system can be found. +To do so, name your CMake file as follows: + +- `XX-default*.cmake` + +A good use case example for these two naming conventions is when you have +a several Linux distributions and all but one can use the same module. +For that case, name one CMake file using the `${OSRELEASE}` value and +name the CMake file to be used with the other distributions using +the `XX-default*.cmake` method. + +## Including Custom Template Scripts + +You can include your own custom template scripts that are passed to the +CMake command `configure_file`. + +Just create your own script and place it in either of the following directories: + +- `$HOME/.config/app-templates/scripts` - the home location +- `/etc/app-templates/scripts` - the system location + +Scripts only need to use the extension `.in` to be

`config.xml` file that describes +your application (widget) and how the Application Framework launches it. +Your repository contains a simple default file named +`config.xml.in` that should work for simple applications and should +not require interactions with other bindings. + +It is also recommended that you use the sample configuration +file that you can find in the location. +This file is named `config.xms.in.sample` and is more complete. +Copy the sample file to your `conf.d/wgt` directory and name it +`config.xml.in`. +Once you have your copy, edit the file to fit your needs. + +**CAUTION:** The default file is only meant to be used for a +simple widget application. +For more complicated applications that need to export +their API, or ship several applications in one widget +need to use the provided `config.xml.in.sample` file, which has +all new Application Framework features explained and provides +examples. + +## Using CMake Template Macros + +To leverage all CMake template features, you must specify properties +on your targets. +Some macros do not work unless you specify the target type. +If you do not specify a type (e.g. a custom target such as an +HTML5 application), the macro uses the `LABELS` property to +determine the target type. + +The `LABELS` property can be set to the values shown in the +[Target Properties](configuring-cmake.html#target-properties) +Section. + +Aside from those values, the following optional values can be +assigned to the `LABELS` property. +These values define the resource types that make up your test materials: + +- **TEST-CONFIG**: JSON configuration files used by the `afb-test` + binding. + These files execute the tests. +- **TEST-DATA**: Resources used to test your binding. + Minimally, you need a test plan. + You should also consider fixtures and any files required by your tests. + These required files appear as part of a separate test widget. +- **TEST-PLUGIN**: A shared library used as a binding plugin. + A binding loads the library as a plugin to extend the binding's functionality. + You should use a special file extension when you name the library + by using the `SUFFIX` CMake target property. + If you do not choose an extension, `.ctlso` is used by default. +- **TEST-HTDOCS**: The root directory of a web application. + This target has to build its directory and put its files in + the `${CMAKE_CURRENT_BINARY_DIR}/${TARGET_NAME}` directory. +- **TEST-EXECUTABLE**: The entry point of your application executed by the AGL + Application Framework. +- **TEST-LIBRARY**: An external third-party library bundled with the binding + for its own purpose. + The platform does not provide this library. + +Following is a mapping between `LABELS` and directories where files reside 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 + +Following is a mapping between test-dedicated `LABELS` and directories where +files reside in the widget: + +- **TEST-EXECUTABLE** : \<wgtrootdir\>/bin +- **TEST-CONFIG** : \<TESTwgtrootdir\>/etc +- **TEST-PLUGIN** : \<wgtrootdir\>/lib/plugins +- **TEST-HTDOCS** : \<wgtrootdir\>/htdocs +- **TEST-DATA** : \<TESTwgtrootdir\>/var + +**TIP:** Use the prefix `afb-` (Application Framework Binding) +with your **BINDING** targets. + +Following is an example that sets the `LABELS` and `OUTPUT_NAME` properties: + +```cmake +SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES + LABELS "HTDOCS" + OUTPUT_NAME dist.prod + ) +``` + +**NOTE**: You do not need to specify an **INSTALL** command for these + targets. + Installation is handled by the template and installs using the + following path : **${CMAKE_INSTALL_PREFIX}/${PROJECT_NAME}** + + Also, if you want to set and use `rpath` with your target, you should use + and set the target property `INSTALL_RPATH`. + +## Adding an External Third-Party Library + +You can add an external third-party library that is built, linked, +and shipped with the project. +Or, you can link and ship the library only with the project. + +### Building, Linking, and Shipping an External Library with the Project + +If you need to include an external library that is not shipped +with the project, you can bundle the required library in the +`lib` widget directory. + +Templates includes facilities to help you work with external +libraries. +A standard method is to declare as many CMake ExternalProject +modules as you need to match the number of needed libraries. + +An ExternalProject module is a special CMake module that lets you define how +to download, update, patch, configure, build, and install an external project. +The project does not need to be a CMake project. +Additionally, you can provide custom steps to account for special +needs using ExternalProject step. +See the CMake +[ExternalProject documentation site](https://cmake.org/cmake/help/v3.5/module/ExternalProject.html?highlight=externalproject) +for more information. + +Following is an example that includes the `mxml` library for the +[unicens2-binding](https://github.com/iotbzh/unicens2-binding) +project: + +```cmake +set(MXML external-mxml) +set(MXML_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/mxml) +ExternalProject_Add(${MXML} + GIT_REPOSITORY https://github.com/michaelrsweet/mxml.git + GIT_TAG release-2.10 + SOURCE_DIR ${MXML_SOURCE_DIR} + CONFIGURE_COMMAND ./configure --build x86_64 --host aarch64 + BUILD_COMMAND make libmxml.so.1.5 + BUILD_IN_SOURCE 1 + INSTALL_COMMAND "" +) + +PROJECT_TARGET_ADD(mxml) + +add_library(${TARGET_NAME} SHARED IMPORTED GLOBAL) + +SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES + LABELS LIBRARY + IMPORTED_LOCATION ${MXML_SOURCE_DIR}/libmxml.so.1 + INTERFACE_INCLUDE_DIRECTORIES ${MXML_SOURCE_DIR} +) + +add_dependencies(${TARGET_NAME} ${MXML}) +``` + +The example defines an external project that drives the building of the library. +The example also defines a new CMake target whose type is **IMPORTED**. +The **IMPORTED** target type indicates the target has yet to be built using +CMake but is available at the location defined using the **IMPORTED_LOCATION** +target property. + +You might want to build the library as **SHARED** or **STATIC** depending on your needs +and goals. +Next, the example only has to modify the external project configure step and change +the filename used by **IMPORTED** library target defined after external project. + +The target's **LABELS** property is set to **LIBRARY** to ship it in the widget. + +In this example, the Unicens project also needs header +information from this library. +Consequently, the **INTERFACE_INCLUDE_DIRECTORIES** target property +is used. +Setting that property when another target links to that imported target +allows access to included directories. + +Finally, the example binds the target to the external project +by using a CMake dependency. + +The target can now be linked and used like any other CMake target. + +### Link and Ship an External Library with the Project + +If you already have a binary version of the library that you want to use and you +cannot or do not want to build the library, you can use the **IMPORTED** +library target. + +To illustrate, consider the same example in the previous section. +Following are the relevant modifications: + +```cmake +PROJECT_TARGET_ADD(mxml) + +add_library(${TARGET_NAME} SHARED IMPORTED GLOBAL) + +SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES + LABELS LIBRARY + IMPORTED_LOCATION /path_to_library/libmxml.so.1 + INTERFACE_INCLUDE_DIRECTORIES /path_to_mxml/include/dir +) +``` + +In the previous example, notice the changes to the +`IMPORTED_LOCATION` and `INTERFACE_INCLUDE_DIRECTORIES` statements. +These locate the binary version of the library. + +Finally, you can link any other library or executable target with this imported +library just as you would for any other target. + +## Macro Reference + +Following are several macros that are useful for advanced CMake usage. + +### PROJECT_TARGET_ADD + +This macro adds the target to your project. +Following is a typical example that adds the target to your project. +You need to provide the name of your target as the macro's parameter: + +Example: + +```cmake +PROJECT_TARGET_ADD(low-can-demo) +``` + +The macro makes the variable `${TARGET_NAME}` available and it is defined +using the specified name (e.g. `low-can-demo`). +The variable changes each time the `PROJECT_TARGET_ADD` macro is called. + +### project_subdirs_add + +This macro searches within specified subfolders of the CMake project for +any `CMakeLists.txt` file. +If the file is found, it is added to your project. +You can use this macro in a hybrid application (e.g. where the binding +exists in a subfolder). + +The following example searches within all subfolders: + +Usage : + +```cmake +project_subdirs_add() +``` + +You might want to restrict the subfolders being searched. +If so, you can specify a +[globbing](https://en.wikipedia.org/wiki/Glob_(programming)) pattern +as the argument. +Doing so effectively creates a search filter. + +Following is an example that specifies all directories that begin +with a number, are followed by the dash character, and then followed +by any characters: + +```cmake +project_subdirs_add("[0-9]-*") +``` + +### set_openapi_filename + +This macro is used with a **BINDINGV2** target and defines the +binding definition filename. +You can use it to also define a relative path to +the current `CMakeLists.txt` file. + +If you do not use this macro to specify the name of your definition file, +the default one is used, which is `${OUTPUT_NAME}-apidef` and uses +**OUTPUT_NAME** as the [target property]. + +**CAUTION** When specifying the binding definition filename, +you must not use the file's extension as part of the name. +Following is an example: + +```cmake +set_openapi_filename('binding/mybinding_definition') +``` + +[target property]: https://cmake.org/cmake/help/v3.6/prop_tgt/OUTPUT_NAME.html "OUTPUT_NAME property documentation" + +### add_input_files + +This macro creates a custom target dedicated for HTML5 and data resource files. +The macro provides syntax and schema verification for different languages that +include LUA, JSON and XML. + +Alongside the macro are tools used to check files. +You can configure the tools by setting the +following variables: + +- XML_CHECKER: Uses **xmllint** that is provided with major linux distributions. +- LUA_CHECKER: Uses **luac** that is provided with major linux distributions. +- JSON_CHECKER: Currently, not used by any tools. + +Following is an example: + +```cmake +add_input_file("${MY_FILES_LIST}") +``` + +**NOTE**: If an issue occurs during the "check" step of the macro, +the build halts. diff --git a/docs/dev_guide/autobuild.md
