Due to the change for the doxygen fix https://github.com/doxygen/doxygen/pull/7888 the file `mag_sel.png` is replaced by `mag_sel.svg`, as a result the search glass in the search box was not present anymore.
(Note this is only valid for versions 1.8.19 and newer).
When having a bit a long citation description, the description runs, in the HTML output on the bibliography page, into 3 or more lines where the 3rd and following lines continue underneath the citation number like:
```
[1] Eric Berberich, Arno Eigenwillig, Michael Hemmer, Susan Hert, Lutz Kettner, Kurt Mehlhorn, Joachim Reichel, Susanne Schmitt, Elmar Schömer, and Nicola Wolpert. Exacus: Efficient and exact
algorithms for curves and surfaces. In Gerth S. Brodal and Stefano Leonardi, editors, 13th Annual European Symposium on Algorithms (ESA 2005), volume 3669 of Lecture Notes in Computer Science,
pages 155–166, Palma de Mallorca, Spain, October 2005. European Association for Theoretical Computer Science (EATCS), Springer.
```
The example was found in e.g. https://doc.cgal.org/latest/Algebraic_foundations/citelist.html
- corrected the "overflow"
- made the citation number right aligned
When (re)generating the documentation from the sources and not using the, internally patched CGAL, doxygen version one gets messages about:
```
warning: ignoring unsupported tag 'EXTRACT_ALL_NO_DETAILED_IF_EMPTY'
```
By introducing the option `CGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY` this doxygen setting can be steered
- option not supplied to cmake, will use as if specified `-DCGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY=ON`
- option supplied to cmake as `-DCGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY=ON` will write the line `EXTRACT_ALL_NO_DETAILED_IF_EMPTY = YES` in the doxygen configuration
- option supplied to cmake as `-DCGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY=OFF` will write the line `#EXTRACT_ALL_NO_DETAILED_IF_EMPTY = NO` in the doxygen configuration, so just using the default setting of `NO` line could be omitted but it is better to have a placeholder
Currently the needed extra definitions for MathJax usage (i.e. `\newcommand` and `\def` commaonds) are distributed over the header file and in a number of source code files.
Doxygen has the possibility for a centralize this by means of the MATHJAX_CODEFILE configuration setting, this has been implemented.
