# FindAnacondaEnvironment
# --------------
#
# Find Python executable and library for a specific Anaconda environment
#
# This module finds the Python interpreter for a specific Anaconda enviroment,
# if installed and determines where the include files and libraries are.
# This code sets the following variables:
#
# ::
# PYTHONINTERP_FOUND - if the Python interpret has been found
# PYTHON_EXECUTABLE - the Python interpret found
# PYTHON_LIBRARY - path to the python library
# PYTHON_INCLUDE_PATH - path to where Python.h is found (deprecated)
# PYTHON_INCLUDE_DIRS - path to where Python.h is found
# PYTHONLIBS_VERSION_STRING - version of the Python libs found (since CMake 2.8.8)
# PYTHON_VERSION_MAJOR - major Python version
# PYTHON_VERSION_MINOR - minor Python version
# PYTHON_VERSION_PATCH - patch Python version
