# 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 - The version of SIP found expressed as a 6 digit hex number
# suitable for comparision as a string.
#
# SIP_VERSION_STR - The version of SIP found as a human readable string.
#
# SIP_BINARY_PATH - Path and filename of the SIP command line executable.
#
# SIP_INCLUDE_DIR - Directory holding the SIP C++ header file.
#
# SIP_DEFAULT_SIP_DIR - Default directory where .sip files should be installed
# into.

# Unfortunately, we cannot use the standard way of calling sipconfig.py, since this seems to hard-code
# the paths during sip build time and these do not have to coincide with wherever BALL_contrib has been
# placed by the user...
#
# This file defines the following variables:
#
# SIP_FOUND = system has sip support, and sip modules could be loaded successfully
#
# SIP_LIBRARIES = full path to the sip libraries
#
# SIP_VERSION = The version of SIP found expressed as a 6 digit hex number
# suitable for comparison as a string.
#
# SIP_VERSION_STR = The version of SIP found as a human readable string.
#
# SIP_EXECUTABLE = Full path of the SIP command line executable.
#
# SIP_INCLUDE_DIR = Directory holding the SIP C++ header file.

# For details see the accompanying COPYING-CMAKE-SCRIPTS file.
