CMakeGraphVizOptions
--------------------
The builtin graphviz support of CMake.
Variables specific to the graphviz support
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
CMake
can generate `graphviz <http://www.graphviz.org/>`_ files, showing the dependencies between the
targets in a project and also external libraries which are linked
against. When CMake is run with the ``--graphviz=foo.dot`` option, it will
produce:
* a ``foo.dot`` file showing all dependencies in the project
* a ``foo.dot.<target>`` file for each target, file showing on which other targets the respective target depends
* a ``foo.dot.<target>.dependers`` file, showing which other targets depend on the respective target
The different dependency types ``PUBLIC``, ``PRIVATE`` and ``INTERFACE``
are represented as solid, dashed and dotted edges.
This can result in huge graphs. Using the file
``CMakeGraphVizOptions.cmake`` the look and content of the generated
graphs can be influenced. This file is searched first in
:variable:`CMAKE_BINARY_DIR` and then in :variable:`CMAKE_SOURCE_DIR`. If found, it is
read and the variables set in it are used to adjust options for the
generated graphviz files.
.. variable:: GRAPHVIZ_GRAPH_TYPE
The graph type.
* Mandatory : NO
* Default : "digraph"
Valid graph types are:
* "graph" : Nodes are joined with lines
* "digraph" : Nodes are joined with arrows showing direction
* "strict graph" : Like "graph" but max one line between each node
* "strict digraph" : Like "graph" but max one line between each node in each direction
.. variable:: GRAPHVIZ_GRAPH_NAME
The graph name.
* Mandatory : NO
* Default : "GG"
.. variable:: GRAPHVIZ_GRAPH_HEADER
The header written at the top of the graphviz file.
* Mandatory : NO
* Default : "node [n fontsize = "12"];"
.. variable:: GRAPHVIZ_NODE_PREFIX
The prefix for each node in the graphviz file.
* Mandatory : NO
* Default : "node"
.. variable:: GRAPHVIZ_EXECUTABLES
Set this to FALSE to exclude executables from the generated graphs.
* Mandatory : NO
* Default : TRUE
.. variable:: GRAPHVIZ_STATIC_LIBS
Set this to FALSE to exclude static libraries from the generated graphs.
* Mandatory : NO
* Default : TRUE
.. variable:: GRAPHVIZ_SHARED_LIBS
Set this to FALSE to exclude shared libraries from the generated graphs.
* Mandatory : NO
* Default : TRUE
.. variable:: GRAPHVIZ_MODULE_LIBS
Set this to FALSE to exclude module libraries from the generated graphs.
* Mandatory : NO
* Default : TRUE
.. variable:: GRAPHVIZ_EXTERNAL_LIBS
Set this to FALSE to exclude external libraries from the generated graphs.
* Mandatory : NO
* Default : TRUE
.. variable:: GRAPHVIZ_IGNORE_TARGETS
A list of regular expressions for ignoring targets.
* Mandatory : NO
* Default : empty
.. variable:: GRAPHVIZ_GENERATE_PER_TARGET
Set this to FALSE to exclude per target graphs ``foo.dot.<target>``.
* Mandatory : NO
* Default : TRUE
.. variable:: GRAPHVIZ_GENERATE_DEPENDERS
Set this to FALSE to exclude depender graphs ``foo.dot.<target>.dependers``.
* Mandatory : NO
* Default : TRUE
