FindPythonInterp

Deprecated since version 3.12: Use FindPython3, FindPython2 or FindPython instead.

Find python interpreter

This module finds if Python interpreter is installed and determines where the executables are. This code sets the following variables:

PYTHONINTERP_FOUND         - Was the Python executable found
PYTHON_EXECUTABLE          - path to the Python interpreter

PYTHON_VERSION_STRING      - Python version found e.g. 2.5.2
PYTHON_VERSION_MAJOR       - Python major version found e.g. 2
PYTHON_VERSION_MINOR       - Python minor version found e.g. 5
PYTHON_VERSION_PATCH       - Python patch version found e.g. 2

The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of version numbers that should be taken into account when searching for Python. You need to set this variable before calling find_package(PythonInterp).

If calling both find_package(PythonInterp) and find_package(PythonLibs), call find_package(PythonInterp) first to get the currently active Python version by default with a consistent version of PYTHON_LIBRARIES.

Note

A call to find_package(PythonInterp ${V}) for python version V may find a python executable with no version suffix. In this case no attempt is made to avoid python executables from other versions. Use FindPython3, FindPython2 or FindPython instead.
