FindPythonInterp — CMake 3.24.2 Documentation

# 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.
