# DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
# DOXYGEN_DOT_FOUND = Was Dot found or not?
-# DOXYGEN_DOT_PATH = The path to dot not including the executable
+#
+# 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 :command:`get_filename_component`
+# to compute it from ``DOXYGEN_DOT_EXECUTABLE`` directly, and
+# perhaps the :command:`file(TO_NATIVE_PATH)` command to prepare
+# the path for a Doxygen configuration file.
