# FindPython3Libs
|
|
# --------------
|
|
#
|
|
# 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:
|
|
#
|
|
# ::
|
|
#
|
|
# PYTHON3LIBS_FOUND - have the Python libs been found
|
|
# PYTHON3_LIBRARIES - path to the python library
|
|
# PYTHON3_INCLUDE_PATH - path to where Python.h is found (deprecated)
|
|
# PYTHON3_INCLUDE_DIRS - path to where Python.h is found
|
|
# PYTHON3_DEBUG_LIBRARIES - path to the debug library (deprecated)
|
|
# PYTHON3LIBS_VERSION_STRING - version of the Python libs found (since CMake 2.8.8)
|
|
#
|
|
#
|
|
#
|
|
# The Python3_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(Python3Libs).
|
|
#
|
|
# If you'd like to specify the installation of Python to use, you should
|
|
# modify the following cache variables:
|
|
#
|
|
# ::
|
|
#
|
|
# PYTHON3_LIBRARY - path to the python library
|
|
# PYTHON3_INCLUDE_DIR - path to where Python.h is found
|
|
#
|
|
# If calling both ``find_package(PythonInterp)`` and
|
|
# ``find_package(Python3Libs)``, call ``find_package(PythonInterp)`` first to
|
|
# get the currently active Python version by default with a consistent version
|
|
# of PYTHON3_LIBRARIES.
