Allow setting the --graphviz="path" option via CMake script variable.
This is a feature request.
In my project I am using the --graphviz
option per default, because I have a custom target that uses the generated files to check for circular dependencies between targets. It would shorten the command line if the option could also be set with a variable in the CMakeLists.txt file to remove the need for adding the option on each command line call.
