0006 # Find the installed version of SIP. FindSIP should be called after Python
0007 # has been found.
0008 #
0009 # This file defines the following variables:
0010 #
0011 # SIP_VERSION - The version of SIP found expressed as a 6 digit hex number
0012 #     suitable for comparison as a string.
0013 #
0014 # SIP_VERSION_STR - The version of SIP found as a human readable string.
0015 #
0016 # SIP_EXECUTABLE - Path and filename of the SIP command line executable.
0017 #
0018 # SIP_INCLUDE_DIR - Directory holding the SIP C++ header file.
0019 #
0020 # SIP_DEFAULT_SIP_DIR - Default directory where .sip files should be installed
0021 #     into.
