# This is copied from cmake 2.8.10, since older versions contain a bug that # stops the EXACT specifier from being honored # (http://www.cmake.org/Bug/view.php?id=13216) # This depends on two other .cmake files; they are also copied here with # a py- prefix. # - Find python libraries # This module finds if Python is installed and determines where the # include files and libraries are. It also determines what the name of # the library is. This code sets the following variables: # # PYTHONLIBS_FOUND - have the Python libs been found # PYTHON_LIBRARIES - path to the python library # PYTHON_INCLUDE_PATH - path to where Python.h is found (deprecated) # PYTHON_INCLUDE_DIRS - path to where Python.h is found # PYTHON_DEBUG_LIBRARIES - path to the debug library (deprecated) # PYTHONLIBS_VERSION_STRING - version of the Python libs found (since CMake 2.8.8) # # The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of # version numbers that should be taken into account when searching for Python. # You need to set this variable before calling find_package(PythonLibs). # # If you'd like to specify the installation of Python to use, you should modify # the following cache variables: # PYTHON_LIBRARY - path to the python library # PYTHON_INCLUDE_DIR - path to where Python.h is found #============================================================================= # Copyright 2001-2009 Kitware, Inc. # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) include(CMakeFindFrameworks) # Search for the python framework on Apple.
