Python version 3.8 is required to export plugins. Add to your setup.py entrypoints section a "kwiver_plugins" namespace. This namespace is defined in the kwiver.vital.plugins.constants module under the PLUGIN_NAMESPACE attribute.

The required python packages areincluded in the source code. The runtime requirements are defined in the kwiver/src/python/requirements_dev.txt file.

Using the appropriate [virtual] environment with python activated, the python packages can be installed with::

$ pip install -r /python/requirements_dev.txt

We assume CMake is available on the system. Otherwise, CMake is also installable via pip. It will be installed via the above requirements file.

PyBind11 is used extensively here to facilitate the binding interface. PyBind11 version 2.10.3 is currently being utilize

python setup.py bdist_wheel -- -C $GIT_CLONE_PATH/.gitlab/ci/configure_wheel.cmake
LD_LIBRARY_PATH=/opt/fletch/lib/ auditwheel show dist/*.whl
LD_LIBRARY_PATH=/opt/fletch/lib/ auditwheel repair dist/*.whl

This should create a dist/ directory here after successful completion. In that directory will be the wheel file for the python version built against.

Scikit-build will perform a "normal build," however "installed" items will be placed such that they are included under the package's root module. For example, if we install the file <prefix>/lib/foo.so, then the package built by Scikit-build will include <site-packages>/kwiver/lib/foo.so.

Note that certain build and installation locations are different for scikit-build runs vs. "normal" build runs. This is done in order to facilitate proper library and module library build and installation locations for python packages. This is managed by the KWIVER CMake functions and should not need additional management by binding developers.

Example: kwiver_add_python_library may result in, for a "normal" build, a library placed into <build_dir>/lib/python3.6/site-packages/kwiver/vital/config/_config.so however for a scikit-build run, the same library would be placed in <source_dir>/_skbuild/.../cmake-build/vital/config/_config.so/.
