+title: Configuring AGL CMake Templates
+---
+
+Configuration consists of editing the `config.cmake` file for your
+specific project.
+
+## Creating Your `config.cmake` File
+
+First, you need to create a `confd/cmake` file in your CMake project
+directory.
+
+```bash
+mkdir -p conf.d/cmake
+```
+
+Next, use one of the following commands to copy a `cmake.sample` file to
+your `config.cmake` file.
+The first command applies if you have the SDK installed, while the
+second command applies if you installed the modules on your native Linux system.
+
+**NOTE:** The `OECORE_NATIVE_SYSROOT` variable is defined once you have
+a project folder, the AGL SDK source files, and the CMake modules installed.
+
+```bash
+mkdir -p conf.d/cmake
+# From the SDK sysroot >= RC2 of the 7.0.0 Guppy release
+cp ${OECORE_NATIVE_SYSROOT}/usr/share/doc/CMakeAfbTemplates/samples.d/config.cmake.sample conf.d/cmake/config.cmake
+```
+
+Once you have created your `config.cmake` file, you need to make the changes
+specific to your project.
+
+## Creating Your `CMakeLists.txt` File
+
+To create this file, use the example in the **cmake module**.
+Use one of the following two commands to create your file.
+The first command applies if you have the SDK installed, while the
+second command applies if you installed the modules on your native Linux system.
+
+**NOTE:** The `OECORE_NATIVE_SYSROOT` variable is defined once you have
+a project folder, the AGL SDK source files, and the CMake modules installed.
+
+```bash
+# From the SDK sysroot >= RC2 of the 7.0.0 Guppy release
+cp ${OECORE_NATIVE_SYSROOT}/usr/share/doc/CMakeAfbTemplates/samples.d/CMakeLists.txt.sample CMakeLists.txt
+```
+
+## Creating Your CMake Targets
+
+Creating a CMake target is the result of editing your `CMakeLists.txt` file.
+
+For each target that is part of your project, you need to use the
+***PROJECT_TARGET_ADD*** statement.
+Using this statement includes the target in your project.
+
+Using the ***PROJECT_TARGET_ADD*** statement makes the CMake ***TARGET_NAME***
+variable available until the next ***PROJECT_TARGET_ADD*** statement is
+encountered that uses a new target name.
+
+Following is typical use within the `CMakeLists.txt` file to create a target:
+
+```cmake
+PROJECT_TARGET_ADD(target_name) --> Adds *target_name* to the project.
+*target_name* is a sub-folder in the CMake project.
+
+add_executable/add_library(${TARGET_NAME}.... --> Defines the target sources.
+
+SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES.... --> Configures the target properties
+so they can be used by macros.
+
+INSTALL(TARGETS ${TARGET_NAME}....
+```
+
+## Target Properties
+
+Target properties are used to determine the nature of the
+target and where the target is stored within the package being built.
+
+Use the **LABELS** property to specify the target type that you want
+included in the widget package.
+You can choose the following target types:
+
+Choose between:
+
+- **BINDING**: A shared library loaded by the AGL Application Framework.
+- **BINDINGV2**: A shared library loaded by the AGL Application Framework.
+ This library must be accompanied by a JSON file named similar to the
+ *${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
+ *${OUTPUT_NAME}-apidef* of the target, which describes the API with OpenAPI
+ syntax (e.g: *mybinding-apidef*).
+ Alternatively, you can choose the name without the extension using the
+ **set_openapi_filename** macro.
+ If you use C++, you must set **PROJECT_LANGUAGES** through *CXX*.
+- **PLUGIN**: A shared library meant to be used as a binding plugin, which
+ would load the library as a plugin consequently extending its
+ functionalities.
+ You should name the binding using a special extension that you choose
+ with `SUFFIX cmake target property`.
+ If you do not use the special extension, it defaults to **.ctlso**.
+- **HTDOCS**: The root directory of a web application.
+ This target has to build its directory and puts its files in the
+ **${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}/${TARGET_NAME}**.
+- **EXECUTABLE**: The entry point of your application executed by the AGL
+ Application Framework.
+- **LIBRARY**: An external third-party library bundled with the binding.
+ The library is bundled in this manner because the platform does not
+ provide bundling.
+- **BINDING-CONFIG**: Any files used as configuration by your binding.
+
+**TIP:** you should use the prefix _afb-_ (**Application Framework Binding**)
+with your *BINDING* targets.
+
+Following is an example that uses the **BINDINGV3** property:
+
+```cmake
+SET_TARGET_PROPERTIES(${TARGET_NAME} PROPERTIES
+ PREFIX "afb-"
+ LABELS "BINDINGV3"
+ OUTPUT_NAME "file_output_name")
+```
+
+**CAUTION**: You do not need to specify an **INSTALL** command for these
+targets.
+Installation is performed by the template.
+Targets are installed in the **${CMAKE_INSTALL_PREFIX}/${PROJECT_NAME}**
+directory. \ No newline at end of file

+title: Advanced Usage
+---
+
+This topic describes some advanced ways of using the CMake templates.
+
+## Building a Widget
+
+To build a widget, you need a `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.
+
+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. \ No newline at end of file

+title: Advanced Customization
+---
+
+This section describes how you can include additional CMake files
+and custom template scripts.
+
+## Including Additional CMake Files
+
+You can include machine and system custom CMake files and
+operating system custom CMake files.
+
+### Machine and System Custom CMake Files
+
+Advanced configuration is possible by automatically including
+additional CMake files from specific locations.
+Following are the locations from which you can add CMake
+files.
+Inclusions occur in the order shown here:
+
+- `<project-root-path>/conf.d/app-templates/cmake/cmake.d` - normally located CMake project files
+- `$HOME/.config/app-templates/cmake.d` - the home location
+- `/etc/app-templates/cmake.d` - the system location
+
+The CMake files you include must be named using either of the following conventions:
+
+- `XX-common*.cmake`
+- `XX-${PROJECT_NAME}*.cmake`
+
+In both formats, `XX` are numbers and indicate the order in which the file
+is included.
+The `*` character represents the filename.
+
+When naming the file, consider the projects in which the file needs to be
+included.
+If you want to include the file in all projects, use the keyword `common`.
+If you want to include the file in a specific project, use the `${PROJECT_NAME}`
+value.
+
+For example, if you want a CMake file whose name is `my_custom_file`
+included first and you want it included in all projects, name the file
+`01-common-my_custom_file.cmake`.
+If you want the same file included in a single project defined by the
+`PROJECT_NAME` variable, and you want it included after all other files,
+name the file `99-${PROJECT_NAME}-my_custom_file.cmake`.
+
+When you include CMake files that use CMake variables, the values override
+variables with the same name.
+The exception to this rule is if you use a cached variable.
+Following is an example:
+
+```cmake
+set(VARIABLE_NAME 'value string random' CACHE STRING 'docstring')
+```
+
+In this example, the `VARIABLE_NAME` variable is defined as a cached
+variable by using the **CACHE** keyword.
+Consequently, `VARIABLE_NAME` does not get overridden as a result of
+including a CMake file that sets the same variable.
+
+### Operating System Custom CMake Files
+
+Including custom CMake files based on the operating system
+lets you personalize a project depending on the operating system
+you are using.
+
+At the end of the `config.cmake` file `common.cmake` includes
+CMake files to customize your project build depending on your platform.
+The operating system is detected by using `/etc/os-release`,
+which is the default method used in almost all Linux distributions.
+Consequently, you can use the value of field **ID_LIKE** to
+add a CMake file for that distribution.
+The file comes from your `conf.d/cmake/` directory or relatively
+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 parsed and configured by
+CMake.

+full build and packaging solution that is independent of the
+[Yocto Project](https://www.yoctoproject.org) workflow.
+
+You can create a script named **autobuild** to control applications
+build operations.
+AGL provides a BitBake class file (`aglwgt.bbclass`) that calls the
+**autobuild** script for all operations.
+The class file is located at the top level of the application repository.
+
+You can write the **autobuild** script using any of the following languages:
+
+* Makefile
+* Bash
+* Python
+
+The script executes directly after applying a `chmod()` command.
+The caller, which can be the `aglwgt.bbclass`, a Jenkins job, or an actual person,
+must make the **autobuild** executable before calling it.
+To facilitate direct execution, you need to start the script with a
+[shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)) sequence:
+
+* '#!/usr/bin/make -f' for Makefile format
+* '#!/usr/bin/bash' for Bash format
+
+The calling convention is similar to the convention used in `make`.
+To pass arguments, use environment variables.
+
+**NOTE:** For Bash, an evaluation of the arguments
+sets the environment variables correctly.
+
+The following format shows the generic call:
+
+```bash
+autobuild/agl/autobuild <command> [ARG1="value1" [ARG2="value2" ... ]]
+```
+
+The **autobuild** script can be invoked from any directory
+with all paths considered to be relative to the
+script's location.
+For makefile scripts, this is the usual behavior.
+For Bash scripts, a `cd $(dirname $0)` command must be run at
+the beginning of the script.
+
+At build time, the following calls must be made in the following order:
+
+1. Initialize the build environment (e.g if the application uses
+ `cmake` the configure step runs CMake).
+
+ ```bash
+ autobuild/agl/autobuild configure CONFIGURE_ARGS="..."
+ ```
+
+2. Build the application (i.e. compile, link binaries, assembles javascript,
+ and so forth).
+
+ ```bash
+ autobuild/agl/autobuild build BUILD_ARGS="...."
+ ```
+
+3. Create the widget package(s) in the specified destination path
+ prepared by the caller.
+
+ ```bash
+ autobuild/agl/autobuild package PACKAGE_ARGS="..." DEST=<path-for-resulting-wgt-files>
+ ```
+
+4. Create the test widget package(s) in the specified destination path
+ prepared by the caller.
+
+ ```bash
+ autobuild/agl/autobuild package-test PACKAGE_ARGS="..." DEST=<path-for-resulting-wgt-files>
+ ```
+
+5. Clean the built files by removing the result of the **autobuild** build.
+
+ ```bash
+ autobuild/agl/autobuild clean CLEAN_ARGS="..."
+ ```
+
+6. Clean everything by removing the result of the **autobuild** build
+ and the **autobuild** configure.
+
+ ```bash
+ autobuild/agl/autobuild distclean DISTCLEAN_ARGS="..."
+ ```
+
+## Integrating **autobuild** into the Yocto Project Workflow
+
+If you want to integrate the **autobuild** script into the Yocto Project
+workflow, you need to generate the script.
+To generate the script, use the `autobuild` target.
+
+The following commands create the **autobuild** script in the
+`autobuild/agl` directory:
+
+```bash
+mkdir -p build
+cd build
+cmake .. && make autobuild
+```
+
+## Available Targets
+
+Following are the targets available from the **autobuild** script:
+
+- **clean**: Removes all the object files and target results generated by Makefile.
+- **clean-{release,debug,coverage,test}**: Removes all the object files and target results generated by Makefile for the specified build type.
+- **clean-all**: Deletes the build directories for all build types.
+- **distclean**: Deletes the build directories for all build types.
+- **configure**: Generates the project Makefile from the `CMakeLists.txt` files for the release build type.
+- **configure-{release,debug,coverage,test}**: Generates the project Makefile from the `CMakeLists.txt` files for the specified build type.
+- **build**: Compiles all project targets for the release build type.
+- **build-{release,debug,coverage,test}**: Compiles all project targets for the specified build type.
+- **build-all**: Compiles all project targets for all specified build types.
+- **package**: Builds the widget (**wgt**) package for the release build type.
+- **package-{release,debug,coverage}**: Builds the widget (**wgt**) package for the specified build type.
+- **package-test**: Builds the test **wgt** package.
+- **package-all**: Builds the widget (**wgt**) packages for all build types.
+- **install**: Installs the project into your filesystem.
+
+Note that `aglwgt.bbclass` only will use the **package-{coverage,test}** targets (and thus the **build-{coverage,test}**, etc. targets) for service bindings by default, so **autobuild** scripts for applications may omit support for those.
+
+Specifying the following variables lets you modify compilation behavior:
+
+- **CLEAN_ARGS**: Variable used at **clean** time.
+- **CONFIGURE_ARGS**: Variable used at **configure** time.
+- **BUILD_ARGS**: Variable used at **build** time.
+- **BUILD_DIR**: Build directory for release type build.
+ The default value is a "build" directory in the root of the project.
+- **BUILD_DIR_DEBUG**: Build directory for debug type build.
+ The default value is a "build-debug" directory in the root of the project.
+- **BUILD_DIR_TEST**: Build directory for test type build.
+ The default value is a "build-test" directory in the root of the project.
+- **BUILD_DIR_COVERAGE**: Build directory for coverage type build.
+ The default value is a "build-coverage" directory in the root of the project.
+- **DEST**: Directory in which to place the created ***wgt*** file(s).
+ The default directory is the build root directory.
+
+Note that the values of **BUILD_DIR_{DEBUG,TEST,COVERAGE}** are defined based on the value of **BUILD_DIR**, so this needs to be kept in mind if over-riding it and building those other widget types.
+
+When you provide a variable, use the CMake format (i.e.
+BUILD_ARGS="-DC_FLAGS='-g -O2'").
+Following is an example:
+
+```bash
+./autobuild/agl/autobuild package DEST=/tmp
+```

+title: Using CMake Templates from BitBake Recipes
+---
+
+If you have developed an application and you want to include it in an AGL image,
+you must add a BitBake recipe in one of the following layers:
+
+* [meta-agl](https://gerrit.automotivelinux.org/gerrit/#/admin/projects/AGL/meta-agl):
+ meta-agl layer (core AGL)
+* [meta-agl-cluster-demo](https://gerrit.automotivelinux.org/gerrit/#/admin/projects/AGL/meta-agl-cluster-demo):
+ cluster demo specific recipes and configuration
+* [meta-agl-demo](https://gerrit.automotivelinux.org/gerrit/#/admin/projects/AGL/meta-agl-demo):
+ meta-agl-demo layer (demo/staging/"one-shot")
+* [meta-agl-devel](https://gerrit.automotivelinux.org/gerrit/#/admin/projects/AGL/meta-agl-devel):
+ meta-agl-devel (Development and Community BSPs)
+* [meta-agl-extra](https://gerrit.automotivelinux.org/gerrit/#/admin/projects/AGL/meta-agl-extra):
+ meta-agl-extra (additional/optional components for AGL)
+
+Once you have the recipe in place, edit it to include the following
+line to cause the `aglwgt` class to be inherited:
+
+```bb
+inherit aglwgt
+```
+
+Following is an example that uses the HVAC application recipe (i.e. `hvac.bb`), which
+builds the HVAC application:
+
+```bb
+SUMMARY = "HVAC Service Binding"
+DESCRIPTION = "AGL HVAC Service Binding"
+HOMEPAGE = "https://gerrit.automotivelinux.org/gerrit/#/admin/projects/apps/agl-service-hvac"
+SECTION = "apps"
+
+LICENSE = "Apache-2.0"
+LIC_FILES_CHKSUM = "file://LICENSE;md5=ae6497158920d9524cf208c09cc4c984"
+
+SRC_URI = "gitsm://gerrit.automotivelinux.org/gerrit/apps/agl-service-hvac;protocol=https;branch=${AGL_BRANCH}"
+SRCREV = "${AGL_APP_REVISION}"
+
+PV = "1.0+git${SRCPV}"
+S = "${WORKDIR}/git"
+
+DEPENDS = "json-c"
+RDEPENDS_${PN} += "agl-service-identity-agent"
+
+inherit cmake aglwgt pkgconfig
+```
+

+CMake templates:
