FindPythonInterp — CMake 4.0.2 Documentation (original) (raw)

Changed in version 3.27: This module is available only if policy CMP0148 is not set to NEW.

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) andfind_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 Vmay 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 FindPythoninstead.
