# Find SIP
# ~~~~~~~~
#
# SIP website: http://www.riverbankcomputing.co.uk/sip/index.php
#
# Find the installed version of SIP. FindSIP should be called after Python
# has been found.
#
# This file defines the following variables:
#
# SIP_VERSION - SIP version.
#
# SIP_EXECUTABLE - Path to the SIP executable.
#
# SIP_INCLUDE_DIRS - The SIP include directories.
