# * Find python libraries This module finds the libraries corresponding to the Python
|
||||
# interpreter FindPythonInterp provides. This code sets the following variables:
|
||||
#
|
||||
# PYTHONLIBS_FOUND - have the Python libs been found PYTHON_PREFIX - path to the
|
||||
# Python installation PYTHON_LIBRARIES - path to the python library
|
||||
# PYTHON_INCLUDE_DIRS - path to where Python.h is found PYTHON_MODULE_EXTENSION -
|
||||
# lib extension, e.g. '.so' or '.pyd' PYTHON_MODULE_PREFIX - lib name prefix: usually an
|
||||
# empty string PYTHON_SITE_PACKAGES - path to installation site-packages
|
||||
# PYTHON_IS_DEBUG - whether the Python interpreter is a debug build
|
||||
#
|
||||
# Thanks to talljimbo for the patch adding the 'LDVERSION' config variable usage.
