|
|
#
|
|
# 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.
