Auto detect layout generator
The auto layout feature depends on layout generators provided by the GraphViz package, which is normally installed alongside Umbrello by a package manager. Umbrello has built-in support for detecting the installed location of these layout generators. For cases where this dependency is not available or does not fit, a different installation path could be selected.
