# - Find Python libraries
|
|
# Find the native Python includes and library
|
|
#
|
|
# Note:, This is not _yet_ intended to be a general python module for other
|
|
# projects to use since its hard coded to python 3.2 as blender only supports
|
|
# a single python version.
|
|
# This is for blender/unix python only.
|
|
#
|
|
# This module defines
|
|
# PYTHON_VERSION
|
|
# PYTHON_INCLUDE_DIRS
|
|
# PYTHON_LIBRARIES
|
|
# PYTHON_LIBPATH, Used for installation
|
|
# PYTHON_LINKFLAGS
|
|
# PYTHON_ROOT_DIR, The base directory to search for Python.
|
|
# This can also be an environment variable.
|
|
#
|
|
# also defined, but not for general use are
|
|
# PYTHON_LIBRARY, where to find the python library.
