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.
