9 # This file defines the following macros:
11 # ADD_SIP_PYTHON_MODULE (MODULE_NAME MODULE_SIP [library1, libaray2, ...])
12 # Specifies a SIP file to be built into a Python module and installed.
13 # MODULE_NAME is the name of Python module including any path name. (e.g.
14 # os.sys, Foo.bar etc). MODULE_SIP the path and filename of the .sip file
15 # to process and compile. libraryN are libraries that the Python module,
16 # which is typically a shared library, should be linked to. The built
17 # module will also be install into Python's site-packages directory.
19 # The behaviour of the ADD_SIP_PYTHON_MODULE macro can be controlled by a
20 # number of variables:
22 # SIP_INCLUDES - List of directories which SIP will scan through when looking
23 # for included .sip files. (Corresponds to the -I option for SIP.)
25 # SIP_TAGS - List of tags to define when running SIP. (Corresponds to the -t
28 # SIP_CONCAT_PARTS - An integer which defines the number of parts the C++ code
29 # of each module should be split into. Defaults to 8. (Corresponds to the
32 # SIP_DISABLE_FEATURES - List of feature names which should be disabled
33 # running SIP. (Corresponds to the -x option for SIP.)
35 # SIP_EXTRA_OPTIONS - Extra command line options which should be passed on to
40 SET(SIP_CONCAT_PARTS 8)
