FindPython2¶
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)
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.
