# - 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).
|
||
|
|
#
|
||
|
|
# You can point to a preferred python install to use by setting the following
|
||
|
|
# to the point at the root directory of the python install:
|
||
|
|
#
|
||
|
|
# PYTHON_ROOT_DIR - The root directory of the python install
|
||
|
|
#
|
||
|
|
# 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
