370 ## \brief Build documentation with doxygen
372 # The doxygen target helper will build software documentation using
373 # the given \a doxyfile (which defaults to \c Doxyfile). The Doxygen
374 # builder used supports automatic dependency generation (dependencies
375 # are automatically generated from the parameters specified in the \a
376 # doxyfile), automatic target emitters (the exact targets created are
377 # found parsing the \a doxyfile) and lots of other features. See the
378 # Doxygen builder documentation
380 # If \a extra_sources are given, the generated documentation will
381 # depend on them. This can be used to build images or other
382 # supplementary files.
384 # The doxygen target helper extends the builder with additional
387 # \li Fix tagfiles by removing namespace entries. These entries only
388 # work for namespaces completely defined in a single module. As
389 # soon as another module (which references the tagfile) has it's
390 # own members in that namespace, the crosslinking will break.
391 # \li If \c DOXY_HTML_XSL is defined as a construction environment
392 # variable, preprocess all generated html files (if html files are
393 # generated) by the given XSLT stylesheet. Since the HTML
394 # generated by doxygen is broken, we first filter the code through
395 # HTML-\c tidy and filter out some error messages.
396 # \li If xml output is generated we create files \c bug.xmli and \c
397 # todo.xmli which contain all bugs and todo items specified in the
398 # sources. The format of these files is much more suited to
399 # postprocessing and is a more database like format as the doxygen
400 # generated files (which are more presentation oriented). if \c
401 # DOXY_XREF_TYPES is given, it will specify the cross reference
402 # types to support (defaults to \c bug and \c todo). See <a
