# Find the Python interpreter and related Python directories.

|
#
|
|
# This file defines the following variables:
|
|
#
|
|
# PYTHON_EXECUTABLE - The path and filename of the Python interpreter.
|
|
#
|
|
# PYTHON_SHORT_VERSION - The version of the Python interpreter found,
|
|
# excluding the patch version number. (e.g. 2.5 and not 2.5.1))
|
|
#
|
|
# PYTHON_LONG_VERSION - The version of the Python interpreter found as a human
|
|
# readable string.
|
|
#
|
|
# PYTHON_SITE_PACKAGES_INSTALL_DIR - this cache variable can be used for installing
|
|
# own python modules. You may want to adjust this to be the
|
|
# same as ${PYTHON_SITE_PACKAGES_DIR}, but then admin
|
|
# privileges may be required for installation.
|
|
#
|
|
# PYTHON_SITE_PACKAGES_DIR - Location of the Python site-packages directory.
|
|
#
|
|
# PYTHON_INCLUDE_PATH - Directory holding the python.h include file.
|
|
#
|
|
# PYTHON_LIBRARY, PYTHON_LIBRARIES- Location of the Python library.
