# CMakeGraphVizOptions
# --------------------
#
# The builtin graphviz support of CMake.
#
# Variables specific to the graphviz support
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#
# CMake
# can generate graphviz files, showing the dependencies between the
# targets in a project and also external libraries which are linked
# against.  When CMake is run with the --graphiz=foo 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
#
# 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
# ${CMAKE_BINARY_DIR} and then in ${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"
#
# .. 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
