# - Find python interpreter
|
|
|
|
|
# This module finds if Python interpreter is installed and determines where the
|
|
|
|
|
# executables are. This code sets the following variables:
|
|
|
|
|
#
|
|
|
|
|
# PYTHONINTERP_FOUND - Was the Python executable found
|
|
|
|
|
# PYTHON_EXECUTABLE - path to the Python interpreter
|
|
|
|
|
# Python_ADDITIONAL_VERSIONS - list of additional Python versions to search for
|
|
