FindPython
Find Python interpreter, compiler and development environment (include
directories and libraries).
Three components are supported:
- Interpreter: search for Python interpreter.
- Compiler: search for Python 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 (Python COMPONENTS Interpreter Development)
This module looks preferably for version 3 of Python. If not found, version 2
is searched.
To manage concurrent versions 3 and 2 of Python, use FindPython3 and
FindPython2 modules rather than this one.
Imported Targets
This module defines the following Imported Targets:
- Python::Interpreter
- Python interpreter. Target defined if component Interpreter is found.
- Python::Compiler
- Python compiler. Target defined if component Compiler is found.
- Python::Python
- Python library. Target defined if component Development is found.
Result Variables
This module will set the following variables in your project
(see Standard Variable Names):
- Python_FOUND
- System has the Python requested components.
- Python_Interpreter_FOUND
- System has the Python interpreter.
- Python_EXECUTABLE
- Path to the Python interpreter.
- Python_INTERPRETER_ID
- A short string unique to the interpreter. Possible values include:
- Python
- ActivePython
- Anaconda
- Canopy
- IronPython
- Python_STDLIB
Standard platform independent installation directory.
Information returned by
distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=True).
- Python_STDARCH
Standard platform dependent installation directory.
Information returned by
distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=True).
- Python_SITELIB
Third-party platform independent installation directory.
Information returned by
distutils.sysconfig.get_python_lib(plat_specific=False,standard_lib=False).
- Python_SITEARCH
Third-party platform dependent installation directory.
Information returned by
distutils.sysconfig.get_python_lib(plat_specific=True,standard_lib=False).
- Python_Compiler_FOUND
- System has the Python compiler.
- Python_COMPILER
- Path to the Python compiler. Only offered by IronPython.
- Python_COMPILER_ID
- A short string unique to the compiler. Possible values include:
-
- Python_Development_FOUND
- System has the Python development artifacts.
- Python_INCLUDE_DIRS
- The Python include directories.
- Python_LIBRARIES
- The Python libraries.
- Python_LIBRARY_DIRS
- The Python library directories.
- Python_RUNTIME_LIBRARY_DIRS
- The Python runtime library directories.
- Python_VERSION
- Python version.
- Python_VERSION_MAJOR

Hints
- Python_ROOT_DIR
- Define the root directory of a Python installation.
- Python_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 Python_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
Python::Python:
Python_add_library (my_module MODULE src1.cpp)
If library type is not specified, MODULE is assumed.
