FindPython2

Find Python 2 interpreter, compiler and development environment (include directories and libraries).

Three components are supported:

• Interpreter: search for Python 2 interpreter
• Compiler: search for Python 2 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 (Python2 COMPONENTS Interpreter Development)

This module looks only for version 2 of Python. This module can be used concurrently with FindPython3 module to use both Python versions.

The FindPython module can be used if Python version does not matter for you.

Imported Targets

This module defines the following Imported Targets:

Python2::Interpreter

Python 2 interpreter. Target defined if component Interpreter is found.

Python2::Compiler

Python 2 compiler. Target defined if component Compiler is found.

Python2::Python

Python 2 library. Target defined if component Development is found.

Result Variables

This module will set the following variables in your project (see Standard Variable Names):

Python2_FOUND

System has the Python 2 requested components.

Python2_Interpreter_FOUND

System has the Python 2 interpreter.

Python2_EXECUTABLE

Path to the Python 2 interpreter.

Python2_INTERPRETER_ID

A short string unique to the interpreter. Possible values include:

• Python
• ActivePython
• Anaconda
• Canopy
• IronPython

Python2_STDLIB

Standard platform independent installation directory.

Information returned by distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=True).

Python2_STDARCH

Standard platform dependent installation directory.

Information returned by distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=True).

Python2_SITELIB

Third-party platform independent installation directory.

Information returned by distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=False).

Python2_SITEARCH

Third-party platform dependent installation directory.

Information returned by distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=False).

Python2_Compiler_FOUND

System has the Python 2 compiler.

Python2_COMPILER

Path to the Python 2 compiler. Only offered by IronPython.

Python2_COMPILER_ID

A short string unique to the compiler. Possible values include:

• IronPython

Python2_Development_FOUND

System has the Python 2 development artifacts.

Python2_INCLUDE_DIRS

The Python 2 include directories.

Python2_LIBRARIES

The Python 2 libraries.

Python2_LIBRARY_DIRS

The Python 2 library directories.

Python2_RUNTIME_LIBRARY_DIRS

The Python 2 runtime library directories.

Python2_VERSION

Python 2 version.

Python2_VERSION_MAJOR

Python 2 major version.

Python2_VERSION_MINOR

Python 2 minor version.

Python2_VERSION_PATCH

Python 2 patch version.

Hints

Python2_ROOT_DIR

Define the root directory of a Python 2 installation.

Python2_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 Python2_add_library which have the same semantic as add_library() but take care of Python module naming rules (only applied if library is of type MODULE) and add dependency to target Python2::Python:

Python2_add_library (my_module MODULE src1.cpp)

If library type is not specified, MODULE is assumed.
