UseSWIG
|
|
-------
|
|
|
|
This file provides support for ``SWIG``. It is assumed that :module:`FindSWIG`
|
|
module has already been loaded.

CMake Commands
|
|
^^^^^^^^^^^^^^
|
|
|
|
The following command is defined for use with ``SWIG``:
|
|
|
|
.. command:: swig_add_library
|
|
|
|
.. versionadded:: 3.8
|
|
|
|
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 the ``swig_add_library`` command have the same
|
|
capabilities as targets created with the :command:`add_library` command, so
|
|
those targets can be used with any command expecting a target (e.g.
|
|
:command:`target_link_libraries`).
|
|
|
|
.. versionchanged:: 3.13
|
|
This command creates a target with the specified ``<name>`` when
|
|
policy :policy:`CMP0078` is set to ``NEW``. Otherwise, the legacy
|
|
behavior will choose a different target name and store it in the
|
|
``SWIG_MODULE_<name>_REAL_NAME`` variable.
|
|
|
|
.. versionchanged:: 3.15
|
|
Alternate library name (set with the :prop_tgt:`OUTPUT_NAME` property,
|
|
for example) will be passed on to ``Python`` and ``CSharp`` wrapper
|
|
libraries.
|
|
|
|
.. versionchanged:: 3.21
|
|
Generated library use standard naming conventions for ``CSharp`` language
|
|
when policy :policy:`CMP0122` is set to ``NEW``. Otherwise, the legacy
|
|
behavior is applied.
|
|
|
|
.. note::
|
|
|
|
For multi-config generators, this module does not support
|
|
configuration-specific files generated by ``SWIG``. All build
|
|
configurations must result in the same generated source file.
|
|
|
|
.. note::
|
|
|
|
For :ref:`Makefile Generators`, if, for some sources, the
|
|
``USE_SWIG_DEPENDENCIES`` property is ``FALSE``, ``swig_add_library`` does
|
|
not track file dependencies, so depending on the ``<name>_swig_compilation``
|
|
custom target is required for targets which require the ``swig``-generated
|
|
files to exist. Other generators may depend on the source files that would
|
|
be generated by SWIG.
|
|
|
|
``TYPE``
|
|
``SHARED``, ``MODULE`` and ``STATIC`` have the same semantic as for the
|
|
:command:`add_library` command. If ``USE_BUILD_SHARED_LIBS`` is specified,
|
|
the library type will be ``STATIC`` or ``SHARED`` based on whether the
|
|
current value of the :variable:`BUILD_SHARED_LIBS` variable is ``ON``. If
|
|
no type is specified, ``MODULE`` will be used.
|
|
|
|
``LANGUAGE``
|
|
Specify the target language.
|
|
|
|
.. versionadded:: 3.1
|
|
Go and Lua language support.
|
|
|
|
.. versionadded:: 3.2
|
|
R language support.
|
|
|
|
.. versionadded:: 3.18
|
|
Fortran language support.
|
|
|
|
``NO_PROXY``
|
|
.. versionadded:: 3.12
|
|
|
|
Prevent the generation of the wrapper layer (swig ``-noproxy`` option).
|
|
|
|
``OUTPUT_DIR``
|
|
.. versionadded:: 3.12
|
|
|
|
Specify where to write the language specific files (swig ``-outdir``
|
|
option). If not given, the ``CMAKE_SWIG_OUTDIR`` variable will be used.
|
|
If neither is specified, the default depends on the value of the
|
|
``UseSWIG_MODULE_VERSION`` variable as follows:
|
|
|
|
* If ``UseSWIG_MODULE_VERSION`` is 1 or is undefined, output is written to
|
|
the :variable:`CMAKE_CURRENT_BINARY_DIR` directory.
|
|
* If ``UseSWIG_MODULE_VERSION`` is 2, a dedicated directory will be used.
|
|
The path of this directory can be retrieved from the
|
|
``SWIG_SUPPORT_FILES_DIRECTORY`` target property.
|
|
|
|
``OUTFILE_DIR``
|
|
.. versionadded:: 3.12
|
|
|
|
Specify an output directory name where the generated source file will be
|
|
placed (swig ``-o`` option). If not specified, the ``SWIG_OUTFILE_DIR``
|
|
variable will be used. If neither is specified, ``OUTPUT_DIR`` or
|
|
``CMAKE_SWIG_OUTDIR`` is used instead.
|
|
|
|
``SOURCES``
|
|
List of sources for the library. Files with extension ``.i`` will be
|
|
identified as sources for the ``SWIG`` tool. Other files will be handled in
|
|
the standard way.
|
|
|
|
.. versionadded:: 3.14
|
|
This behavior can be overridden by specifying the variable
|
|
``SWIG_SOURCE_FILE_EXTENSIONS``.
|
|
|
|
.. note::
|
|
|
|
If ``UseSWIG_MODULE_VERSION`` is set to 2, it is **strongly** recommended
|
|
to use a dedicated directory unique to the target when either the
|
|
``OUTPUT_DIR`` option or the ``CMAKE_SWIG_OUTDIR`` variable are specified.
|
|
The output directory contents are erased as part of the target build, so
|
|
to prevent interference between targets or losing other important files,
|
|
each target should have its own dedicated output directory.
|
|
|
|
Properties on Source Files
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Source file 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 the 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)
|
|
|
|
``SWIG_FLAGS``
|
|
.. deprecated:: 3.12
|
|
Replaced with the fine-grained properties that follow.
|
|
|
|
Pass custom flags to the SWIG executable.
|
|
|
|
``INCLUDE_DIRECTORIES``, ``COMPILE_DEFINITIONS`` and ``COMPILE_OPTIONS``
|
|
.. versionadded:: 3.12
|
|
|
|
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`.
|
|
|
|
``USE_TARGET_INCLUDE_DIRECTORIES``
|
|
.. versionadded:: 3.13
|
|
|
|
If set to ``TRUE``, contents of target property
|
|
:prop_tgt:`INCLUDE_DIRECTORIES` will be forwarded to ``SWIG`` compiler.
|
|
If set to ``FALSE`` target property :prop_tgt:`INCLUDE_DIRECTORIES` will be
|
|
ignored. If not set, target property ``SWIG_USE_TARGET_INCLUDE_DIRECTORIES``
|
|
will be considered.
|
|
|
|
``GENERATED_INCLUDE_DIRECTORIES``, ``GENERATED_COMPILE_DEFINITIONS`` and ``GENERATED_COMPILE_OPTIONS``
|
|
.. versionadded:: 3.12
|
|
|
|
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``
|
|
.. versionadded:: 3.12
|
|
|
|
Specify additional dependencies to the source file.
|
|
|
|
``USE_SWIG_DEPENDENCIES``
|
|
.. versionadded:: 3.20
|
|
|
|
If set to ``TRUE``, implicit dependencies are generated by the ``swig`` tool
|
|
itself. This property is only meaningful for
|
|
:ref:`Makefile <Makefile Generators>`,
|
|
:ref:`Ninja <Ninja Generators>`, :generator:`Xcode`, and
|
|
:ref:`Visual Studio <Visual Studio Generators>`
|
|
(:generator:`Visual Studio 12 2013` and above) generators. Default value is
|
|
``FALSE``.
|
|
|
|
.. versionadded:: 3.21
|
|
Added the support of :generator:`Xcode` generator.
|
|
|
|
.. versionadded:: 3.22
|
|
Added the support of :ref:`Visual Studio Generators`.
|
|
|
|
``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)
|
|
|
|
.. versionchanged:: 3.14
|
|
If policy :policy:`CMP0086` is set to ``NEW``, ``-module <module_name>``
|
|
is passed to ``SWIG`` compiler.
|
|
|
|
``OUTPUT_DIR``
|
|
.. versionadded:: 3.19
|
|
|
|
Specify where to write the language specific files (swig ``-outdir`` option)
|
|
for the considered source file. If not specified, the other ways to define
|
|
the output directory applies (see ``OUTPUT_DIR`` option of
|
|
``swig_add_library()`` command).
|
|
|
|
``OUTFILE_DIR``
|
|
.. versionadded:: 3.19
|
|
|
|
Specify an output directory where the generated source file will be placed
|
|
(swig ``-o`` option) for the considered source file. If not specified,
|
|
``OUTPUT_DIR`` source property will be used. If neither are specified, the
|
|
other ways to define output file directory applies (see ``OUTFILE_DIR``
|
|
option of ``swig_add_library()`` command).
|
|
|
|
Properties on Targets
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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``
|
|
.. versionadded:: 3.12
|
|
|
|
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
|
|
|
|
set (UseSWIG_TARGET_NAME_PREFERENCE STANDARD)
|
|
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_USE_TARGET_INCLUDE_DIRECTORIES``
|
|
.. versionadded:: 3.13
|
|
|
|
If set to ``TRUE``, contents of target property
|
|
:prop_tgt:`INCLUDE_DIRECTORIES` will be forwarded to ``SWIG`` compiler.
|
|
If set to ``FALSE`` or not defined, target property
|
|
:prop_tgt:`INCLUDE_DIRECTORIES` will be ignored. This behavior can be
|
|
overridden by specifying source property ``USE_TARGET_INCLUDE_DIRECTORIES``.
|
|
|
|
``SWIG_GENERATED_INCLUDE_DIRECTORIES``, ``SWIG_GENERATED_COMPILE_DEFINITIONS`` and ``SWIG_GENERATED_COMPILE_OPTIONS``
|
|
.. versionadded:: 3.12
|
|
|
|
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``
|
|
.. versionadded:: 3.12
|
|
|
|
Add dependencies to all SWIG input files.
|
|
|
|
Read-only Target Properties
|
|
"""""""""""""""""""""""""""
|
|
|
|
The following target properties are output properties and can be used to get
|
|
information about support files generated by ``SWIG`` interface compilation.
|
|
|
|
``SWIG_SUPPORT_FILES``
|
|
.. versionadded:: 3.12
|
|
|
|
This output property list of wrapper files generated during SWIG compilation.
|
|
|
|
.. code-block:: cmake
|
|
|
|
set (UseSWIG_TARGET_NAME_PREFERENCE STANDARD)
|
|
swig_add_library(mymod LANGUAGE python SOURCES mymod.i)
|
|
get_property(support_files TARGET mymod PROPERTY SWIG_SUPPORT_FILES)
|
|
|
|
.. note::
|
|
|
|
Only most principal support files are listed. In case some advanced
|
|
features of ``SWIG`` are used (for example ``%template``), associated
|
|
support files may not be listed. Prefer to use the
|
|
``SWIG_SUPPORT_FILES_DIRECTORY`` property to handle support files.
|
|
|
|
``SWIG_SUPPORT_FILES_DIRECTORY``
|
|
.. versionadded:: 3.12
|
|
|
|
This output property specifies the directory where support files will be
|
|
generated.
|
|
|
|
.. note::
|
|
|
|
When source property ``OUTPUT_DIR`` is defined, multiple directories can be
|
|
specified as part of ``SWIG_SUPPORT_FILES_DIRECTORY``.
|
|
|
|
CMake Variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
Some variables can be set to customize the behavior of ``swig_add_library``
|
|
as well as ``SWIG``:
|
|
|
|
``UseSWIG_MODULE_VERSION``
|
|
.. versionadded:: 3.12
|
|
|
|
Specify different behaviors for ``UseSWIG`` module.
|
|
|
|
* Set to 1 or undefined: Legacy behavior is applied.
|
|
* Set to 2: A new strategy is applied regarding support files: the output
|
|
directory of support files is erased before ``SWIG`` interface compilation.
|
|
|
|
``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``
|
|
.. versionadded:: 3.8
|
|
|
|
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>``.
|
|
|
|
``SWIG_SOURCE_FILE_EXTENSIONS``
|
|
.. versionadded:: 3.14
|
|
|
|
Specify a list of source file extensions to override the default
|
|
behavior of considering only ``.i`` files as sources for the ``SWIG``
|
|
tool. For example:
|
|
|
|
.. code-block:: cmake
|
|
|
|
set(SWIG_SOURCE_FILE_EXTENSIONS ".i" ".swg")
|
|
|
|
``SWIG_USE_SWIG_DEPENDENCIES``
|
|
.. versionadded:: 3.20
|
|
|
|
If set to ``TRUE``, implicit dependencies are generated by the ``swig`` tool
|
|
itself. This variable is only meaningful for
|
|
:ref:`Makefile <Makefile Generators>`,
|
|
:ref:`Ninja <Ninja Generators>`, :generator:`Xcode`, and
|
|
:ref:`Visual Studio <Visual Studio Generators>`
|
|
(:generator:`Visual Studio 12 2013` and above) generators. Default value is
|
|
``FALSE``.
|
|
|
|
Source file property ``USE_SWIG_DEPENDENCIES``, if not defined, will be
|
|
initialized with the value of this variable.
|
|
|
|
.. versionadded:: 3.21
|
|
Added the support of :generator:`Xcode` generator.
|
|
|
|
.. versionadded:: 3.22
|
|
Added the support of :ref:`Visual Studio Generators`.
|
|
|
|
Deprecated Commands
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. command:: swig_link_libraries
|
|
|
|
.. deprecated:: 3.13
|
|
Use :command:`target_link_libraries` with the standard target name,
|
|
or with ``${SWIG_MODULE_<name>_REAL_NAME}`` for legacy target naming.
|
|
|
|
Link libraries to swig module::
|
|
|
|
swig_link_libraries(<name> <item>...)
|
|
|
|
This command has same capabilities as :command:`target_link_libraries`
|
|
command.
|
|
|
|
.. note::
|
|
When policy :policy:`CMP0078` is set to ``NEW``,
|
|
:command:`swig_add_library` creates a standard target with the
|
|
specified ``<name>`` and :command:`target_link_libraries` must be used
|
|
instead of this command.
|
|
|
|
With the legacy behavior (when :policy:`CMP0078` is set to ``OLD`` and
|
|
the ``UseSWIG_TARGET_NAME_PREFERENCE`` variable is set to ``"LEGACY"``,
|
|
or in CMake versions prior to 3.12), it is preferable to use
|
|
``target_link_libraries(${SWIG_MODULE_<name>_REAL_NAME} ...)``
|
|
instead of this command.
