+# FindPython3Interp
+# ----------------
+#
+# Find python interpreter
+#
+# This module finds if Python interpreter is installed and determines
+# where the executables are. This code sets the following variables:
+#
+# ::
+#
+# PYTHON3INTERP_FOUND - Was the Python executable found
+# PYTHON3_EXECUTABLE - path to the Python interpreter
+#
+#
+#
+# ::
+#
+# PYTHON3_VERSION_STRING - Python version found e.g. 2.5.2
+# PYTHON3_VERSION_MAJOR - Python major version found e.g. 2
+# PYTHON3_VERSION_MINOR - Python minor version found e.g. 5
+# PYTHON3_VERSION_PATCH - Python patch version found e.g. 2
+#
+#
+#
+# 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(Python3Interp).
+#
+# If calling both ``find_package(Python3Interp)`` and
+# ``find_package(Python3Libs)``, call ``find_package(Python3Interp)`` first to
+# get the currently active Python version by default with a consistent version
+# of PYTHON3_LIBRARIES.
