# SIP website: http://www.riverbankcomputing.co.uk/sip/index.php
#
# This file defines the following macros:
#
# ADD_SIP_PYTHON_MODULE (MODULE_NAME MODULE_SIP [library1, libaray2, ...])
#     Specifies a SIP file to be built into a Python module and installed.
#     MODULE_NAME is the name of Python module including any path name. (e.g.
#     os.sys, Foo.bar etc). MODULE_SIP the path and filename of the .sip file
#     to process and compile. libraryN are libraries that the Python module,
#     which is typically a shared library, should be linked to. The built
#     module will also be install into Python's site-packages directory.
#
# The behaviour of the ADD_SIP_PYTHON_MODULE macro can be controlled by a
# number of variables:
#
# SIP_INCLUDES - List of directories which SIP will scan through when looking
#     for included .sip files. (Corresponds to the -I option for SIP.)
#
# SIP_TAGS - List of tags to define when running SIP. (Corresponds to the -t
#     option for SIP.)
#
# SIP_CONCAT_PARTS - An integer which defines the number of parts the C++ code
#     of each module should be split into. Defaults to 8. (Corresponds to the
#     -j option for SIP.)
#
# SIP_DISABLE_FEATURES - List of feature names which should be disabled
#     running SIP. (Corresponds to the -x option for SIP.)
#
# SIP_EXTRA_OPTIONS - Extra command line options which should be passed on to
#     SIP.
