built. + +Use the **LABELS** property to specify the target type that you want +included in the widget package. +You can choose the following target types: + +Choose between: + +- **BINDING**: A shared library loaded by the AGL Application Framework. +- **BINDINGV2**: A shared library loaded by the AGL Application Framework. + This library must be accompanied by a JSON file named similar to the + *${OUTPUT_NAME}-apidef* of the target, which describes the API with OpenAPI + syntax (e.g: *mybinding-apidef*). + Alternatively, you can choose the name without the extension using the + **set_openapi_filename** macro. + If you use C++, you must set **PROJECT_LANGUAGES** through *CXX*. +- **BINDINGV3**: A shared library loaded by the AGL Application Framework. + This library must be accompanied by a JSON file named similar to the + *${OUTPUT_NAME}-apidef* of the target, which describes the API with OpenAPI + syntax (e.g: *mybinding-apidef*). + Alternatively, you can choose the

plugin, which + would load the library as a plugin consequently extending its + functionalities. + You should name the binding using a special extension that you choose + with `SUFFIX cmake target property`. + If you do not use the special extension, it defaults to **.ctlso**. +- **HTDOCS**: The root directory of a web application. + 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**: The entry point of your application executed by the AGL + Application Framework. +- **LIBRARY**: An external third-party library

Then you have to bundle the required library in the `lib` widget +directory. + +Templates includes some facilities to help you to do so. Classic way to do so +is to declare as many CMake ExternalProject as library you need. + +An ExternalProject is a special CMake module that let you define how to: +download, update, patch, configure, build and install an external project. It +doesn't have to be a CMake project and custom step could be added for special +needs using ExternalProject step. More informations on CMake [ExternalProject +documentation site](https://cmake.org/cmake/help/v3.5/module/ExternalProject.html?highlight=externalproject). + +Example to include `mxml` library for [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} ${MXML}) +``` + +Here we define an external project that drive the build of the library then we +define new CMake target of type **IMPORTED**. Meaning that this target hasn't +been built using CMake but is available at the location defined in the target +property *IMPORTED_LOCATION*. + +You could want to build the library as *SHARED* or *STATIC* depending on your needs +and goals. Then you only have to modify the external project configure step and change +filename used by **IMPORTED** library target defined after external project. + +Then target *LABELS* property is set to **LIBRARY** to ship it in the widget. + +Unicens project also need some header from this library, so we use the target +property *INTERFACE_INCLUDE_DIRECTORIES*. Setting that when another target link +to that imported target, it can access to the include directories. + +We bound the target to the external project using a CMake dependency at last. + +Then this target could be use like any other CMake target and be linked etc. + +### Only link and ship external library with the project + +If you already have a binary version of the library that you want to use and you +can't or don't want to build the library then you only have to add an **IMPORTED** +library target. + +So, taking the above example, `mxml` library inclusion would be: + +```cmake +PROJECT_TARGET_ADD(mxml) + +add_library(${TARGET_NAME} SHARED IMPORTED GLOBAL) + +SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES + LABELS LIBRARY + IMPORTED_LOCATION /path/to/library/libmxml.so.1 + INTERFACE_INCLUDE_DIRECTORIES /path/to/mxml/include/dir +) +``` + +Finally, you can link any other lib or executable target with this imported +library like any other target. + +## Macro reference + +### PROJECT_TARGET_ADD + +Typical usage would be to add the target to your project using macro +`PROJECT_TARGET_ADD` with the name of your target as parameter. + +Example: + +```cmake +PROJECT_TARGET_ADD(low-can-demo) +``` + +> ***NOTE***: This will make available the variable `${TARGET_NAME}` +> set with the specificied name.
