For a detailed description of version range usage and capabilities, refer to the :command:`find_package` command. The following components are supported: * ``Interpreter``: search for Python interpreter. * ``Compiler``: search for Python compiler. Only offered by IronPython. * ``Development``: search for development artifacts (include directories and libraries). .. versionadded:: 3.18 This component includes two sub-components which can be specified independently: * ``Development.Module``: search for artifacts for Python module developments. * ``Development.Embed``: search for artifacts for Python embedding developments. .. versionadded:: 3.26 * ``Development.SABIModule``: search for artifacts for Python module developments using the `Stable Application Binary Interface <https://docs.python.org/3/c-api/stable.html>`_. This component is available only for version ``3.2`` and upper. * ``NumPy``: search for NumPy include directories. .. versionadded:: 3.14 Added the ``NumPy`` component. If no ``COMPONENTS`` are specified, ``Interpreter`` is assumed. If component ``Development`` is specified, it implies sub-components ``Development.Module`` and ``Development.Embed``. To ensure consistent versions between components ``Interpreter``, ``Compiler``, ``Development`` (or one of its sub-components) and ``NumPy``, specify all components at the same time:: find_package (Python COMPONENTS Interpreter Development) This module looks preferably for version 3 of Python. If not found, version 2 is searched. To manage concurrent versions 3 and 2 of Python, use :module:`FindPython3` and :module:`FindPython2` modules rather than this one. .. note:: If components ``Interpreter`` and ``Development`` (or one of its sub-components) are both specified, this module search only for interpreter with same platform architecture as the one defined by CMake configuration. This constraint does not apply if only ``Interpreter`` component is specified. Imported Targets ^^^^^^^^^^^^^^^^ This module defines the following :ref:`Imported Targets <Imported Targets>`: .. versionchanged:: 3.14 :ref:`Imported Targets <Imported Targets>` are only created when :prop_gbl:`CMAKE_ROLE` is ``PROJECT``. ``Python::Interpreter`` Python interpreter. Target defined if component ``Interpreter`` is found. ``Python::Compiler`` Python compiler. Target defined if component ``Compiler`` is found. ``Python::Module`` .. versionadded:: 3.15 Python library for Python module. Target defined if component ``Development.Module`` is found. ``Python::SABIModule`` .. versionadded:: 3.26 Python library for Python module using the Stable Application Binary Interface. Target defined if component ``Development.SABIModule`` is found. ``Python::Python`` Python library for Python embedding. Target defined if component ``Development.Embed`` is found. ``Python::NumPy`` .. versionadded:: 3.14 NumPy Python library. Target defined if component ``NumPy`` is found.

Possible values include: * Python * ActivePython * Anaconda * Canopy * IronPython * PyPy ``Python_STDLIB`` Standard platform independent installation directory. Information returned by ``distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=True)`` or else ``sysconfig.get_path('stdlib')``. ``Python_STDARCH`` Standard platform dependent installation directory. Information returned by ``distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=True)`` or else ``sysconfig.get_path('platstdlib')``. ``Python_SITELIB`` Third-party platform independent installation directory. Information returned by ``distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=False)`` or else ``sysconfig.get_path('purelib')``. ``Python_SITEARCH`` Third-party platform dependent installation directory. Information returned by ``distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=False)`` or else ``sysconfig.get_path('platlib')``. ``Python_SOABI`` .. versionadded:: 3.17 Extension suffix for modules. Information computed from ``distutils.sysconfig.get_config_var('EXT_SUFFIX')`` or ``distutils.sysconfig.get_config_var('SOABI')`` or ``python3-config --extension-suffix``. If package ``distutils.sysconfig`` is not available, ``sysconfig.get_config_var('EXT_SUFFIX')`` or ``sysconfig.get_config_var('SOABI')`` are used. ``Python_SOSABI`` .. versionadded:: 3.26 Extension suffix for modules using the Stable Application Binary Interface. Information computed from ``importlib.machinery.EXTENSION_SUFFIXES`` if the COMPONENT ``Interpreter`` was specified. Otherwise, the extension is ``abi3`` except for ``Windows``, ``MSYS`` and ``CYGWIN`` for which this is an empty string. ``Python_Compiler_FOUND`` System has the Python compiler. ``Python_COMPILER`` Path to the Python compiler. Only offered by IronPython. ``Python_COMPILER_ID`` A short string unique to the compiler. Possible values include: * IronPython ``Python_DOTNET_LAUNCHER`` .. versionadded:: 3.18 The ``.Net`` interpreter. Only used by ``IronPython`` implementation. ``Python_Development_FOUND`` System has the Python development artifacts. ``Python_Development.Module_FOUND`` .. versionadded:: 3.18 System has the Python development artifacts for Python module. ``Python_Development.SABIModule_FOUND`` .. versionadded:: 3.26 System has the Python development artifacts for Python module using the Stable Application Binary Interface. ``Python_Development.Embed_FOUND`` .. versionadded:: 3.18 System has the Python development artifacts for Python embedding. ``Python_INCLUDE_DIRS`` The Python include directories. ``Python_LINK_OPTIONS`` .. versionadded:: 3.19 The Python link options. Some configurations require specific link options for a correct build and execution. ``Python_LIBRARIES`` The Python libraries. ``Python_LIBRARY_DIRS`` The Python library directories. ``Python_RUNTIME_LIBRARY_DIRS`` The Python runtime library directories. ``Python_SABI_LIBRARIES`` .. versionadded:: 3.26 The Python libraries for the Stable Application Binary Interface. ``Python_SABI_LIBRARY_DIRS`` .. versionadded:: 3.26 The Python ``SABI`` library directories. ``Python_RUNTIME_SABI_LIBRARY_DIRS`` .. versionadded:: 3.26 The Python runtime ``SABI`` library directories. ``Python_VERSION`` Python version. ``Python_VERSION_MAJOR`` Python major version. ``Python_VERSION_MINOR`` Python minor version. ``Python_VERSION_PATCH`` Python patch version. ``Python_PyPy_VERSION`` .. versionadded:: 3.18 Python PyPy version. ``Python_NumPy_FOUND`` .. versionadded:: 3.14 System has the NumPy. ``Python_NumPy_INCLUDE_DIRS`` .. versionadded:: 3.14 The NumPy include directories. ``Python_NumPy_VERSION`` .. versionadded:: 3.14 The NumPy version. Hints ^^^^^ ``Python_ROOT_DIR`` Define the root directory of a Python installation. ``Python_USE_STATIC_LIBS`` * If not defined, search for shared libraries and static libraries in that order. * If set to TRUE, search **only** for static libraries. * If set to FALSE, search **only** for shared libraries. .. note:: This hint will be ignored on ``Windows`` because static libraries are not available on this platform. ``Python_FIND_ABI`` .. versionadded:: 3.16 This variable defines which ABIs, as defined in :pep:`3149`, should be searched. .. note:: This hint will be honored only when searched for ``Python`` version 3. .. note:: If ``Python_FIND_ABI`` is not defined, any ABI will be searched. The ``Python_FIND_ABI`` variable is a 3-tuple specifying, in that order, ``pydebug`` (``d``), ``pymalloc`` (``m``) and ``unicode`` (``u``) flags. Each element can be set to one of the following: * ``ON``: Corresponding flag is selected. * ``OFF``: Corresponding flag is not selected. * ``ANY``: The two possibilities (``ON`` and ``OFF``) will be searched. From this 3-tuple, various ABIs will be searched starting from the most specialized to the most general. Moreover, ``debug`` versions will be searched **after** ``non-debug`` ones. For example, if we have:: set (Python_FIND_ABI "ON" "ANY" "ANY") The following flags combinations will be appended, in that order, to the artifact names: ``dmu``, ``dm``, ``du``, and ``d``. And to search any possible ABIs:: set (Python_FIND_ABI "ANY" "ANY" "ANY") The following combinations, in that order, will be used: ``mu``, ``m``, ``u``, ``<empty>``, ``dmu``, ``dm``, ``du`` and ``d``. .. note:: This hint is useful only on ``POSIX`` systems. So, on ``Windows`` systems, when ``Python_FIND_ABI`` is defined, ``Python`` distributions from `python.org <https://www.python.org/>`_ will be found only if value for each flag is ``OFF`` or ``ANY``. ``Python_FIND_STRATEGY`` .. versionadded:: 3.15 This variable defines how lookup will be done. The ``Python_FIND_STRATEGY`` variable can be set to one of the following: * ``VERSION``: Try to find the most recent version in all specified locations. This is the default if policy :policy:`CMP0094` is undefined or set to ``OLD``. * ``LOCATION``: Stops lookup as soon as a version satisfying version constraints is founded. This is the default if policy :policy:`CMP0094` is set to ``NEW``. ``Python_FIND_REGISTRY`` .. versionadded:: 3.13 On Windows the ``Python_FIND_REGISTRY`` variable determine the order of preference between registry and environment variables. the ``Python_FIND_REGISTRY`` variable can be set to one of the following: * ``FIRST``: Try to use registry before environment variables. This is the default. * ``LAST``: Try to use registry after environment variables. * ``NEVER``: Never try to use registry. ``Python_FIND_FRAMEWORK`` .. versionadded:: 3.15 On macOS the ``Python_FIND_FRAMEWORK`` variable determine the order of preference between Apple-style and unix-style package components. This variable can take same values as :variable:`CMAKE_FIND_FRAMEWORK` variable. .. note:: Value ``ONLY`` is not supported so ``FIRST`` will be used instead. If ``Python_FIND_FRAMEWORK`` is not defined, :variable:`CMAKE_FIND_FRAMEWORK` variable will be used, if any. ``Python_FIND_VIRTUALENV`` .. versionadded:: 3.15 This variable defines the handling of virtual environments managed by ``virtualenv`` or ``conda``. It is meaningful only when a virtual environment is active (i.e. the ``activate`` script has been evaluated). In this case, it takes precedence over ``Python_FIND_REGISTRY`` and ``CMAKE_FIND_FRAMEWORK`` variables. The ``Python_FIND_VIRTUALENV`` variable can be set to one of the following: * ``FIRST``: The virtual environment is used before any other standard paths to look-up for the interpreter. This is the default. * ``ONLY``: Only the virtual environment is used to look-up for the interpreter. * ``STANDARD``: The virtual environment is not used to look-up for the interpreter but environment variable ``PATH`` is always considered. In this case, variable ``Python_FIND_REGISTRY`` (Windows) or ``CMAKE_FIND_FRAMEWORK`` (macOS) can be set with value ``LAST`` or ``NEVER`` to select preferably the interpreter from the virtual environment. .. versionadded:: 3.17 Added support for ``conda`` environments. .. note:: If the component ``Development`` is requested, it is **strongly** recommended to also include the component ``Interpreter`` to get expected result. ``Python_FIND_IMPLEMENTATIONS`` .. versionadded:: 3.18 This variable defines, in an ordered list, the different implementations which will be searched. The ``Python_FIND_IMPLEMENTATIONS`` variable can hold the following values: * ``CPython``: this is the standard implementation. Various products, like ``Anaconda`` or ``ActivePython``, rely on this implementation. * ``IronPython``: This implementation use the ``CSharp`` language for ``.NET Framework`` on top of the `Dynamic Language Runtime` (``DLR``). See `IronPython <https://ironpython.net>`_. * ``PyPy``: This implementation use ``RPython`` language and ``RPython translation toolchain`` to produce the python interpreter. See `PyPy <https://www.pypy.org>`_. The default value is: * Windows platform: ``CPython``, ``IronPython`` * Other platforms: ``CPython`` .. note:: This hint has the lowest priority of all hints, so even if, for example, you specify ``IronPython`` first and ``CPython`` in second, a python product based on ``CPython`` can be selected because, for example with ``Python_FIND_STRATEGY=LOCATION``, each location will be search first for ``IronPython`` and second for ``CPython``. .. note:: When ``IronPython`` is specified, on platforms other than ``Windows``, the ``.Net`` interpreter (i.e. ``mono`` command) is expected to be available through the ``PATH`` variable. ``Python_FIND_UNVERSIONED_NAMES`` .. versionadded:: 3.20 This variable defines how the generic names will be searched. Currently, it only applies to the generic names of the interpreter, namely, ``python3`` or ``python2`` and ``python``. The ``Python_FIND_UNVERSIONED_NAMES`` variable can be set to one of the following values: * ``FIRST``: The generic names are searched before the more specialized ones (such as ``python2.5`` for example). * ``LAST``: The generic names are searched after the more specialized ones. This is the default. * ``NEVER``: The generic name are not searched at all. Artifacts Specification ^^^^^^^^^^^^^^^^^^^^^^^ .. versionadded:: 3.16 To solve special cases, it is possible to specify directly the artifacts by setting the following variables: ``Python_EXECUTABLE`` The path to the interpreter. ``Python_COMPILER`` The path to the compiler. ``Python_DOTNET_LAUNCHER`` .. versionadded:: 3.18 The ``.Net`` interpreter. Only used by ``IronPython`` implementation. ``Python_LIBRARY`` The path to the library. It will be used to compute the variables ``Python_LIBRARIES``, ``Python_LIBRARY_DIRS`` and ``Python_RUNTIME_LIBRARY_DIRS``. ``Python_SABI_LIBRARY`` .. versionadded:: 3.26 The path to the library for Stable Application Binary Interface. It will be used to compute the variables ``Python_SABI_LIBRARIES``, ``Python_SABI_LIBRARY_DIRS`` and ``Python_RUNTIME_SABI_LIBRARY_DIRS``. ``Python_INCLUDE_DIR`` The path to the directory of the ``Python`` headers. It will be used to compute the variable ``Python_INCLUDE_DIRS``. ``Python_NumPy_INCLUDE_DIR`` The path to the directory of the ``NumPy`` headers. It will be used to compute the variable ``Python_NumPy_INCLUDE_DIRS``. .. note:: All paths must be absolute. Any artifact specified with a relative path will be ignored. .. note:: When an artifact is specified, all ``HINTS`` will be ignored and no search will be performed for this artifact. If more than one artifact is specified, it is the user's responsibility to ensure the consistency of the various artifacts. By default, this module supports multiple calls in different directories of a project with different version/component requirements while providing correct and consistent results for each call. To support this behavior, CMake cache is not used in the traditional way which can be problematic for interactive specification. So, to enable also interactive specification, module behavior can be controlled with the following variable: ``Python_ARTIFACTS_INTERACTIVE`` .. versionadded:: 3.18 Selects the behavior of the module. This is a boolean variable: * If set to ``TRUE``: Create CMake cache entries for the above artifact specification variables so that users can edit them interactively. This disables support for multiple version/component requirements. * If set to ``FALSE`` or undefined: Enable multiple version/component requirements. Commands ^^^^^^^^ This module defines the command ``Python_add_library`` (when :prop_gbl:`CMAKE_ROLE` is ``PROJECT``), which has the same semantics as :command:`add_library` and adds a dependency to target ``Python::Python`` or, when library type is ``MODULE``, to target ``Python::Module`` or ``Python::SABIModule`` (when ``USE_SABI`` option is specified) and takes care of Python module naming rules:: Python_add_library (<name> [STATIC | SHARED | MODULE [USE_SABI <version>] [WITH_SOABI]] <source1> [<source2> ...]) If the library type is not specified, ``MODULE`` is assumed. .. versionadded:: 3.17 For ``MODULE`` library type, if option ``WITH_SOABI`` is specified, the module suffix will include the ``Python_SOABI`` value, if any. .. versionadded:: 3.26 For ``MODULE`` type, if the option ``USE_SABI`` is specified, the preprocessor definition ``Py_LIMITED_API`` will be specified, as ``PRIVATE``, for the target ``<name>`` with the value computed from ``<version>`` argument. The expected format for ``<version>`` is ``major[.minor]``, where each component is a numeric value. If ``minor`` component is specified, the version should be, at least, ``3.2`` which is the version where the `Stable Application Binary Interface <https://docs.python.org/3/c-api/stable.html>`_ was introduced. Specifying only major version ``3`` is equivalent to ``3.2``. When option ``WITH_SOABI`` is also specified, the module suffix will include the ``Python3_SOSABI`` value, if any. #]=======================================================================] cmake_policy(PUSH) # numbers and boolean constants cmake_policy (SET CMP0012 NEW) set (_PYTHON_PREFIX Python) unset (_Python_REQUIRED_VERSION_MAJOR) unset (_Python_REQUIRED_VERSIONS) if (Python_FIND_VERSION_RANGE) # compute list of major versions foreach (_Python_MAJOR IN ITEMS 3 2) if (_Python_MAJOR VERSION_GREATER_EQUAL Python_FIND_VERSION_MIN_MAJOR AND ((Python_FIND_VERSION_RANGE_MAX STREQUAL "INCLUDE" AND _Python_MAJOR VERSION_LESS_EQUAL Python_FIND_VERSION_MAX) OR (Python_FIND_VERSION_RANGE_MAX STREQUAL "EXCLUDE" AND _Python_MAJOR VERSION_LESS Python_FIND_VERSION_MAX))) list (APPEND _Python_REQUIRED_VERSIONS ${_Python_MAJOR}) endif() endforeach() list (LENGTH _Python_REQUIRED_VERSIONS _Python_VERSION_COUNT) if (_Python_VERSION_COUNT EQUAL 0) unset (_Python_REQUIRED_VERSIONS) elseif (_Python_VERSION_COUNT EQUAL 1) set (_Python_REQUIRED_VERSION_MAJOR ${_Python_REQUIRED_VERSIONS}) endif() elseif (DEFINED Python_FIND_VERSION) set (_Python_REQUIRED_VERSION_MAJOR ${Python_FIND_VERSION_MAJOR}) else() set (_Python_REQUIRED_VERSIONS 3 2) endif() if (_Python_REQUIRED_VERSION_MAJOR) include (${CMAKE_CURRENT_LIST_DIR}/FindPython/Support.cmake) elseif (_Python_REQUIRED_VERSIONS) # iterate over versions in quiet and NOT required modes to avoid multiple # "Found" messages and prematurally failure. set (_Python_QUIETLY ${Python_FIND_QUIETLY}) set (_Python_REQUIRED ${Python_FIND_REQUIRED}) set (Python_FIND_QUIETLY TRUE) set (Python_FIND_REQUIRED FALSE) set (_Python_REQUIRED_VERSION_LAST 2) unset (_Python_INPUT_VARS) foreach (_Python_ITEM IN ITEMS Python_EXECUTABLE Python_COMPILER Python_LIBRARY Python_INCLUDE_DIR Python_NumPy_INCLUDE_DIR) if (NOT DEFINED ${_Python_ITEM}) list (APPEND _Python_INPUT_VARS ${_Python_ITEM}) endif() endforeach() foreach (_Python_REQUIRED_VERSION_MAJOR IN LISTS _Python_REQUIRED_VERSIONS) set (Python_FIND_VERSION ${_Python_REQUIRED_VERSION_MAJOR}) include (${CMAKE_CURRENT_LIST_DIR}/FindPython/Support.cmake) if (Python_FOUND OR _Python_REQUIRED_VERSION_MAJOR EQUAL _Python_REQUIRED_VERSION_LAST) break() endif() # clean-up INPUT variables not set by the user foreach (_Python_ITEM IN LISTS _Python_INPUT_VARS) unset (${_Python_ITEM}) endforeach() # clean-up some CACHE variables to ensure look-up restart from scratch foreach (_Python_ITEM IN LISTS _Python_CACHED_VARS) unset (${_Python_ITEM} CACHE) endforeach() endforeach() unset (Python_FIND_VERSION) set (Python_FIND_QUIETLY ${_Python_QUIETLY}) set (Python_FIND_REQUIRED ${_Python_REQUIRED}) if (Python_FIND_REQUIRED OR NOT Python_FIND_QUIETLY) # call again validation command to get "Found" or error message find_package_handle_standard_args (Python HANDLE_COMPONENTS HANDLE_VERSION_RANGE REQUIRED_VARS ${_Python_REQUIRED_VARS} VERSION_VAR Python_VERSION) endif() else() # supported versions not in the specified range.
