UseSWIG
-------
Defines the following command for use with SWIG:
.. command:: swig_add_library
Define swig module with given name and specified language::
swig_add_library(<name>
[TYPE <SHARED|MODULE|STATIC|USE_BUILD_SHARED_LIBS>]
LANGUAGE <language>
[NO_PROXY]
[OUTPUT_DIR <directory>]
[OUTFILE_DIR <directory>]
SOURCES <file>...
)
Targets created with command ``swig_add_library`` have the same capabilities as targets
created with command :command:`add_library`, so can be used with any command accepting a target
especially command :command:`target_link_libraries`.
The arguments are:
``TYPE``
``SHARED``, ``MODULE`` and ``STATIC`` have same semantic as command :command:`add_library`.
if ``USE_BUILD_SHARED_LIBS`` is specified, library type will be ``STATIC`` or ``SHARED``
based on whether the current value of the variable :variable:`BUILD_SHARED_LIBS` is ``ON``.
If none is specified, ``MODULE`` will be used.
``LANGUAGE``
Specify the target language.
``NO_PROXY``
Prevent the generation of the wrapper layer (swig ``-noproxy`` option).
``OUTPUT_DIR``
Specify where to write the language specific files (swig ``-outdir`` option).
If not specified, variable ``CMAKE_SWIG_OUTDIR`` will be used. If none is specified,
:variable:`CMAKE_CURRENT_BINARY_DIR` is used.
``OUTFILE_DIR``
Specify an output directory name where the generated source file will be placed
(swig -o option). If not specified, variable ``SWIG_OUTFILE_DIR`` will be used.
If none is specified, option ``OUTPUT_DIR`` or variable ``CMAKE_SWIG_OUTDIR`` is used.
``SOURCES``
List of sources for the library. Files with extension ``.i`` will be identified as sources
for ``SWIG`` tool. Other files will be handled in the standard way.
Source files properties on module files **must** be set before the invocation
of the ``swig_add_library`` command to specify special behavior of SWIG and ensure
generated files will receive required settings.
``CPLUSPLUS``
Call SWIG in c++ mode. For example:
.. code-block:: cmake
set_property(SOURCE mymod.i PROPERTY CPLUSPLUS ON)
swig_add_library(mymod LANGUAGE python SOURCES mymod.i)
``INCLUDE_DIRECTORIES``, ``COMPILE_DEFINITIONS`` and ``COMPILE_OPTIONS``
Add custom flags to SWIG compiler and have same semantic as properties
:prop_sf:`INCLUDE_DIRECTORIES`, :prop_sf:`COMPILE_DEFINITIONS` and :prop_sf:`COMPILE_OPTIONS`.
``GENERATED_INCLUDE_DIRECTORIES``, ``GENERATED_COMPILE_DEFINITIONS`` and ``GENERATED_COMPILE_OPTIONS``
Add custom flags to the C/C++ generated source. They will fill, respectively,
properties :prop_sf:`INCLUDE_DIRECTORIES`, :prop_sf:`COMPILE_DEFINITIONS` and
:prop_sf:`COMPILE_OPTIONS` of generated C/C++ file.
``DEPENDS``
Specify additional dependencies to the source file.
``SWIG_MODULE_NAME``
Specify the actual import name of the module in the target language.
This is required if it cannot be scanned automatically from source
or different from the module file basename. For example:
.. code-block:: cmake
set_property(SOURCE mymod.i PROPERTY SWIG_MODULE_NAME mymod_realname)
Target library properties can be set to apply same configuration to all SWIG input files.
``SWIG_INCLUDE_DIRECTORIES``, ``SWIG_COMPILE_DEFINITIONS`` and ``SWIG_COMPILE_OPTIONS``
These properties will be applied to all SWIG input files and have same semantic as
target properties :prop_tgt:`INCLUDE_DIRECTORIES`, :prop_tgt:`COMPILE_DEFINITIONS` and
:prop_tgt:`COMPILE_OPTIONS`.
.. code-block:: cmake
swig_add_library(mymod LANGUAGE python SOURCES mymod.i)
set_property(TARGET mymod PROPERTY SWIG_COMPILE_DEFINITIONS MY_DEF1 MY_DEF2)
set_property(TARGET mymod PROPERTY SWIG_COMPILE_OPTIONS -bla -blb)
``SWIG_GENERATED_INCLUDE_DIRECTORIES``, ``SWIG_GENERATED_COMPILE_DEFINITIONS`` and ``SWIG_GENERATED_COMPILE_OPTIONS``
These properties will populate, respectively, properties :prop_sf:`INCLUDE_DIRECTORIES`,
:prop_sf:`COMPILE_DEFINITIONS` and :prop_sf:`COMPILE_FLAGS` of all generated C/C++ files.
``SWIG_DEPENDS``
Add dependencies to all SWIG input files.
``SWIG_SUPPORT_FILES``
This output property list of wrapper files generated during SWIG compilation.
.. code-block:: cmake
swig_add_library(mymod LANGUAGE python SOURCES mymod.i)
get_property(support_files TARGET mymod PROPERTY SWIG_SUPPORT_FILES)
Some variables can be set to specify special behavior of SWIG:
``CMAKE_SWIG_FLAGS``
Add flags to all swig calls.
``CMAKE_SWIG_OUTDIR``
Specify where to write the language specific files (swig ``-outdir`` option).
``SWIG_OUTFILE_DIR``
Specify an output directory name where the generated source file will be
placed. If not specified, ``CMAKE_SWIG_OUTDIR`` is used.
``SWIG_MODULE_<name>_EXTRA_DEPS``
Specify extra dependencies for the generated module for ``<name>``.
