+# --------------
+#
+# 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.
