+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)
+
+If no ``COMPONENTS`` is specified, ``Interpreter`` is assumed.
+
+To ensure consistent versions between components ``Interpreter``, ``Compiler``
+and ``Development``, 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.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :ref:`Imported Targets <Imported Targets>`:
+
+``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.
+
+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.
+
+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.
+
+Commands
+^^^^^^^^
+
+This module defines the command ``Python3_add_library`` which have the same
+semantic as :command:`add_library` but take care of Python module naming rules
+(only applied if library is of type ``MODULE``) and add dependency to target
+``Python3::Python``::
+
+  Python3_add_library (my_module MODULE src1.cpp)
+
+If library type is not specified, ``MODULE`` is assumed.
