| 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. |
