CMakeGraphVizOptions
--------------------
The builtin Graphviz support of CMake.
Generating Graphviz files
^^^^^^^^^^^^^^^^^^^^^^^^^
CMake can generate `Graphviz <https://www.graphviz.org/>`_ files showing the
dependencies between the targets in a project, as well as external libraries
which are linked against.
When running CMake with the ``--graphviz=foo.dot`` option, it produces:
* a ``foo.dot`` file, showing all dependencies in the project
* a ``foo.dot.<target>`` file for each target, showing on which other targets
it depends
* a ``foo.dot.<target>.dependers`` file for each target, showing which other
targets depend on it
Those .dot files can be converted to images using the *dot* command from the
Graphviz package:
.. code-block:: shell
dot -Tpng -o foo.png foo.dot
The different dependency types ``PUBLIC``, ``INTERFACE`` and ``PRIVATE``
are represented as solid, dashed and dotted edges.
Variables specific to the Graphviz support
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The resulting graphs can be huge. The look and content of the generated graphs
can be controlled using the file ``CMakeGraphVizOptions.cmake``. This file is
first searched in :variable:`CMAKE_BINARY_DIR`, and then in
:variable:`CMAKE_SOURCE_DIR`. If found, the variables set in it are used to
adjust options for the generated Graphviz files.
.. variable:: GRAPHVIZ_GRAPH_NAME
The graph name.
* Mandatory: NO
* Default: value of :variable:`CMAKE_PROJECT_NAME`
.. variable:: GRAPHVIZ_GRAPH_HEADER
The header written at the top of the Graphviz files.
* Mandatory: NO
* Default: "node [ fontsize = "12" ];"
.. variable:: GRAPHVIZ_NODE_PREFIX
The prefix for each node in the Graphviz files.
* Mandatory: NO
* Default: "node"
.. variable:: GRAPHVIZ_EXECUTABLES
Set to FALSE to exclude executables from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_STATIC_LIBS
Set to FALSE to exclude static libraries from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_SHARED_LIBS
Set to FALSE to exclude shared libraries from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_MODULE_LIBS
Set to FALSE to exclude module libraries from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_INTERFACE_LIBS
Set to FALSE to exclude interface libraries from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_OBJECT_LIBS
Set to FALSE to exclude object libraries from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_UNKNOWN_LIBS
Set to FALSE to exclude unknown libraries from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_EXTERNAL_LIBS
Set to FALSE to exclude external libraries from the generated graphs.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_CUSTOM_TARGETS
Set to TRUE to include custom targets in the generated graphs.
* Mandatory: NO
* Default: FALSE
.. variable:: GRAPHVIZ_IGNORE_TARGETS
A list of regular expressions for names of targets to exclude from the
generated graphs.
* Mandatory: NO
* Default: empty
.. variable:: GRAPHVIZ_GENERATE_PER_TARGET
Set to FALSE to not generate per-target graphs ``foo.dot.<target>``.
* Mandatory: NO
* Default: TRUE
.. variable:: GRAPHVIZ_GENERATE_DEPENDERS
Set to FALSE to not generate depender graphs ``foo.dot.<target>.dependers``.
* Mandatory: NO
* Default: TRUE
