            Bug ID: 18511
           Summary: CMake looks for Graphviz on Windows, but it should use
                    dotty
           Product: Build scripts
           Version: trunk
          Hardware: PC
                OS: other
            Status: NEW
          Severity: normal
          Priority: P
         Component: cmake

I don't know what is the case on other platforms, but on Windows there is no
executable called Graphviz. I think the correct alternative is dotty.exe. The
CMake scripts look for Graphviz, as well as use it for things like -ast-view.
This obviously doesn't work on Windows. CMake should use the (already existing)
dotty.exe path variable instead of looking for Graphviz.

P.S. I wanted to mark this bug report as Windows OS, but the options are only
WinXP, Win2000 or WinNT. Which one is Win7?
