#graphviz - Graph visualization toolkit
#
#Relies on a bunch of third party packages (more than those listed here) which
#it wants to obtain from inside CMake during the build (via the git submodule
#mechanism). Horrible stuff... The CMake build script should be modified to
#use the CMake FetchContent mechanism instead of relying on git directly.
#However, the package maintainers seem to want to offer more build systems
#than CMake and instead rely on git.
