+FindPython3
+-----------
+
+Find Python 3 interpreter, compiler and development environment (include
+directories and libraries).
+
+Three components are supported:
+
+* ``Interpreter``: search for Python 3 interpreter
+* ``Compiler``: search for Python 3 compiler. Only offered by IronPython.
+* ``Development``: search for development artifacts (include directories and
+ libraries)
+* ``NumPy``: search for NumPy include directories.
+
+If no ``COMPONENTS`` is specified, ``Interpreter`` is assumed.
+
+To ensure consistent versions between components ``Interpreter``, ``Compiler``,
+``Development`` and ``NumPy``, specify all components at the same time::
+
+ find_package (Python3 COMPONENTS Interpreter Development)
+
+This module looks only for version 3 of Python. This module can be used
+concurrently with :module:`FindPython2` module to use both Python versions.
+
+The :module:`FindPython` module can be used if Python version does not matter
+for you.
+
+.. note::
+
+ If components ``Interpreter`` and ``Development`` are both specified, this
+ module search only for interpreter with same platform architecture as the one
+ defined by ``CMake`` configuration. This contraint does not apply if only
+ ``Interpreter`` component is specified.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :ref:`Imported Targets <Imported Targets>`
+(when :prop_gbl:`CMAKE_ROLE` is ``PROJECT``):
+
+``Python3::Interpreter``
+ Python 3 interpreter. Target defined if component ``Interpreter`` is found.
+``Python3::Compiler``
+ Python 3 compiler. Target defined if component ``Compiler`` is found.
+``Python3::Python``
+ Python 3 library. Target defined if component ``Development`` is found.
+``Python3::NumPy``
+ NumPy library for Python 3. Target defined if component ``NumPy`` is found.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project
+(see :ref:`Standard Variable Names <CMake Developer Standard Variable Names>`):
+
+``Python3_FOUND``
+ System has the Python 3 requested components.
+``Python3_Interpreter_FOUND``
+ System has the Python 3 interpreter.
+``Python3_EXECUTABLE``
+ Path to the Python 3 interpreter.
+``Python3_INTERPRETER_ID``
+ A short string unique to the interpreter. Possible values include:
+ * Python
+ * ActivePython
+ * Anaconda
+ * Canopy
+ * IronPython
+``Python3_STDLIB``
+ Standard platform independent installation directory.
+
+ Information returned by
+ ``distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=True)``.
+``Python3_STDARCH``
+ Standard platform dependent installation directory.
+
+ Information returned by
+ ``distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=True)``.
+``Python3_SITELIB``
+ Third-party platform independent installation directory.
+
+ Information returned by
+ ``distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=False)``.
+``Python3_SITEARCH``
+ Third-party platform dependent installation directory.
+
+ Information returned by
+ ``distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=False)``.
+``Python3_Compiler_FOUND``
+ System has the Python 3 compiler.
+``Python3_COMPILER``
+ Path to the Python 3 compiler. Only offered by IronPython.
+``Python3_COMPILER_ID``
+ A short string unique to the compiler. Possible values include:
+ * IronPython
+``Python3_Development_FOUND``
+ System has the Python 3 development artifacts.
+``Python3_INCLUDE_DIRS``
+ The Python 3 include directories.
+``Python3_LIBRARIES``
+ The Python 3 libraries.
+``Python3_LIBRARY_DIRS``
+ The Python 3 library directories.
+``Python3_RUNTIME_LIBRARY_DIRS``
+ The Python 3 runtime library directories.
+``Python3_VERSION``
+ Python 3 version.
+``Python3_VERSION_MAJOR``
+ Python 3 major version.
+``Python3_VERSION_MINOR``
+ Python 3 minor version.
+``Python3_VERSION_PATCH``
+ Python 3 patch version.
+``Python3_NumPy_FOUND``
+ System has the NumPy.
+``Python3_NumPy_INCLUDE_DIRS``
+ The NumPy include directries.
+``Python3_NumPy_VERSION``
+ The NumPy version.
+
+Hints
+^^^^^
+
+``Python3_ROOT_DIR``
+ Define the root directory of a Python 3 installation.
+
+``Python3_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.
+
+``Python3_FIND_REGISTRY``
+ On Windows the ``Python3_FIND_REGISTRY`` variable determine the order
+ of preference between registry and environment variables.
+ the ``Python3_FIND_REGISTRY`` variable can be set to empty or 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.
+
+``CMAKE_FIND_FRAMEWORK``
+ On OS X the :variable:`CMAKE_FIND_FRAMEWORK` variable determine the order of
+ preference between Apple-style and unix-style package components.
+
+ .. note::
+
+ Value ``ONLY`` is not supported so ``FIRST`` will be used instead.
+
+.. note::
+
+ If a Python virtual environment is configured, set variable
+ ``Python_FIND_REGISTRY`` (Windows) or ``CMAKE_FIND_FRAMEWORK`` (macOS) with
+ value ``LAST`` or ``NEVER`` to select it preferably.
+
+Commands
+^^^^^^^^
+
+This module defines the command ``Python3_add_library`` (when
+:prop_gbl:`CMAKE_ROLE` is ``PROJECT``), which has the same semantics as
+:command:`add_library`, but takes care of Python module naming rules
+(only applied if library is of type ``MODULE``), and adds a dependency to target
+``Python3::Python``::
+
+ Python3_add_library (my_module MODULE src1.cpp)
+
+If library type is not specified, ``MODULE`` is assumed.
