.. meta:: :description: Learn how to build a plugin using CMake and OpenVINO Developer Package.

OpenVINO build infrastructure provides the OpenVINO Developer Package for plugin development.

OpenVINO Developer Package ##########################

To automatically generate the OpenVINO Developer Package, run the cmake tool during a OpenVINO build:

.. code-block:: sh

$ mkdir openvino-release-build $ cd openvino-release-build $ cmake -DCMAKE_BUILD_TYPE=Release ../openvino

Once the commands above are executed, the OpenVINO Developer Package is generated in the openvino-release-build folder. It consists of several files:

• OpenVINODeveloperPackageConfig.cmake - the main CMake script which imports targets and provides compilation flags and CMake options.

• OpenVINODeveloperPackageConfig-version.cmake - a file with a package version.

• targets_developer.cmake - an automatically generated file which contains all targets exported from the OpenVINO build tree. This file is included by OpenVINODeveloperPackageConfig.cmake to import the following targets:

  • Libraries for plugin development:

    • openvino::runtime - shared OpenVINO library
    • openvino::runtime::dev - interface library with OpenVINO Developer API
    • openvino::pugixml - static Pugixml library
    • openvino::xbyak - interface library with Xbyak headers
    • openvino::itt - static library with tools for performance measurement using Intel ITT

  • Libraries for tests development:

    • openvino::gtest, openvino::gtest_main, openvino::gmock - Google Tests framework libraries
    • openvino::commonTestUtils - static library with common tests utilities
    • openvino::funcTestUtils - static library with functional tests utilities
    • openvino::unitTestUtils - static library with unit tests utilities
    • openvino::ngraphFunctions - static library with the set of ov::Model builders
    • openvino::funcSharedTests - static library with common functional tests
    • openvino::ngraph_reference - static library with operation reference implementations.

.. note::

It's enough just to run cmake --build . --target ov_dev_targets command to build only targets from the OpenVINO Developer package.

Build Plugin using OpenVINO Developer Package #############################################

To build a plugin source tree using the OpenVINO Developer Package, run the commands below:

.. code-block:: sh

$ mkdir template-plugin-release-build $ cd template-plugin-release-build $ cmake -DOpenVINODeveloperPackage_DIR=../openvino-release-build ../template-plugin

A common plugin consists of the following components:

1. Plugin code in the src folder
2. Code of tests in the tests folder

To build a plugin and its tests, run the following CMake scripts:

• Root CMakeLists.txt, which finds the OpenVINO Developer Package using the find_package CMake command and adds the src and tests subdirectories with plugin sources and their tests respectively:

.. doxygensnippet:: src/plugins/template/CMakeLists.txt :language: cpp :fragment: [cmake:main]

.. note::

The default values of the ENABLE_TESTS, ENABLE_FUNCTIONAL_TESTS options are shared via the OpenVINO Developer Package and they are the same as for the main OpenVINO build tree. You can override them during plugin build using the command below:

.. code-block:: sh

$ cmake -DENABLE_FUNCTIONAL_TESTS=OFF -DOpenVINODeveloperPackage_DIR=../openvino-release-build ../template-plugin

• src/CMakeLists.txt to build a plugin shared library from sources:

.. doxygensnippet:: src/plugins/template/src/CMakeLists.txt :language: cpp :fragment: [cmake:plugin]

.. note::

openvino::... targets are imported from the OpenVINO Developer Package.

• tests/functional/CMakeLists.txt to build a set of functional plugin tests:

.. doxygensnippet:: src/plugins/template/tests/functional/CMakeLists.txt :language: cpp :fragment: [cmake:functional_tests]

.. note::

The openvino::funcSharedTests static library with common functional OpenVINO Plugin tests is imported via the OpenVINO Developer Package.
