# FindDoxygen

This module looks for Doxygen and the path to Graphviz’s dot

Doxygen is a documentation generation tool. Please see http://www.doxygen.org

This module accepts the following optional variables:

    DOXYGEN_SKIP_DOT       = If true this module will skip trying to find Dot
                             (an optional component often used by Doxygen)

This modules defines the following variables:

    DOXYGEN_EXECUTABLE     = The path to the doxygen command.
    DOXYGEN_FOUND          = Was Doxygen found or not?
    DOXYGEN_VERSION        = The version reported by doxygen --version

    DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
    DOXYGEN_DOT_FOUND      = Was Dot found or not?

For compatibility with older versions of CMake, the now-deprecated variable `DOXYGEN_DOT_PATH` is set to the path to the directory containing `dot` as reported in `DOXYGEN_DOT_EXECUTABLE`. The path may have forward slashes even on Windows and is not suitable for direct substitution into a `Doxyfile.in` template. If you need this value, use `get_filename_component()` to compute it from `DOXYGEN_DOT_EXECUTABLE` directly, and perhaps the `file(TO_NATIVE_PATH)` command to prepare the path for a Doxygen configuration file.
