Find Python 2 interpreter, compiler and development environment (include directories and libraries).
Three components are supported:
Interpreter
: search for Python 2 interpreterCompiler
: search for Python 2 compiler. Only offered by IronPython.Development
: search for development artifacts (include directories and libraries)NumPy
: search for NumPy include directories.If no COMPONENTS
is specified, Interpreter
is assumed.
To ensure consistent versions between components Interpreter
, Compiler
, Development
and NumPy
, 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.
Note
If components Interpreter
and Development
are both specified, this module search only for interpreter with same platform architecture as the one defined by CMake
configuration. This contraint does not apply if only Interpreter
component is specified.
This module defines the following Imported Targets (when CMAKE_ROLE
is PROJECT
):
Python2::Interpreter
Interpreter
is found.Python2::Compiler
Compiler
is found.Python2::Python
Development
is found.Python2::Module
Development
is found.Python2::NumPy
NumPy
is found.This module will set the following variables in your project (see Standard Variable Names):
Python2_FOUND
Python2_Interpreter_FOUND
Python2_EXECUTABLE
Python2_INTERPRETER_ID
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
Python2_COMPILER
Python2_COMPILER_ID
Python2_Development_FOUND
Python2_INCLUDE_DIRS
Python2_LIBRARIES
Python2_LIBRARY_DIRS
Python2_RUNTIME_LIBRARY_DIRS
Python2_VERSION
Python2_VERSION_MAJOR
Python2_VERSION_MINOR
Python2_VERSION_PATCH
Python2_NumPy_FOUND
Python2_NumPy_INCLUDE_DIRS
Python2_NumPy_VERSION
Python2_ROOT_DIR
Python2_USE_STATIC_LIBS
Python2_FIND_STRATEGY
This variable defines how lookup will be done. The Python2_FIND_STRATEGY
variable can be set to empty or one of the following:
Python2_FIND_REGISTRY
On Windows the Python2_FIND_REGISTRY
variable determine the order of preference between registry and environment variables. the Python2_FIND_REGISTRY
variable can be set to empty or one of the following:
FIRST
: Try to use registry before environment variables. This is the default.LAST
: Try to use registry after environment variables.NEVER
: Never try to use registry.Python2_FIND_FRAMEWORK
On macOS the Python2_FIND_FRAMEWORK
variable determine the order of preference between Apple-style and unix-style package components. This variable can be set to empty or take same values as CMAKE_FIND_FRAMEWORK
variable.
Note
Value ONLY
is not supported so FIRST
will be used instead.
If Python2_FIND_FRAMEWORK
is not defined, CMAKE_FIND_FRAMEWORK
variable will be used, if any.
Python2_FIND_VIRTUALENV
This variable defines the handling of virtual environments. It is meaningfull only when a virtual environment is active (i.e. the activate
script has been evaluated). In this case, it takes precedence over Python2_FIND_REGISTRY
and CMAKE_FIND_FRAMEWORK
variables. The Python2_FIND_VIRTUALENV
variable can be set to empty or one of the following:
FIRST
: The virtual environment is used before any other standard paths to look-up for the interpreter. This is the default.ONLY
: Only the virtual environment is used to look-up for the interpreter.STANDARD
: The virtual environment is not used to look-up for the interpreter. In this case, variable Python2_FIND_REGISTRY
(Windows) or CMAKE_FIND_FRAMEWORK
(macOS) can be set with value LAST
or NEVER
to select preferably the interpreter from the virtual environment.This module defines the command Python_add_library
(when CMAKE_ROLE
is PROJECT
), which has the same semantics as add_library()
and adds a dependency to target Python2::Python
or, when library type is MODULE
, to target Python2::Module
and takes care of Python module naming rules:
Python2_add_library (my_module MODULE src1.cpp)
If library type is not specified, MODULE
is assumed.
