+# - Run Doxygen
+#
+# Adds a doxygen target that runs doxygen to generate the html
+# and optionally the LaTeX API documentation.
+# The doxygen target is added to the doc target as dependency.
+# i.e.: the API documentation is built with:
+#  make doc
+#
+# USAGE: GLOBAL INSTALL
+#
+# Install it with:
+#  cmake ./ && sudo make install
+# Add the following to the CMakeLists.txt of your project:
+#  include(UseDoxygen OPTIONAL)
+# Optionally copy Doxyfile.in in the directory of CMakeLists.txt and edit it.
+#
+# USAGE: INCLUDE IN PROJECT
+#
+#  set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
+#  include(UseDoxygen)
+# Add the Doxyfile.in and UseDoxygen.cmake files to the projects source directory.
+#
+#
+# Variables you may define are:
+#  DOXYFILE_OUTPUT_DIR - Path where the Doxygen output is stored. Defaults to "doc".
+#
+#  DOXYFILE_LATEX_DIR - Directory where the Doxygen LaTeX output is stored. Defaults to "latex".
+#
+#  DOXYFILE_HTML_DIR - Directory where the Doxygen html output is stored. Defaults to "html".
