renders in an unexpected way (see
Kernel_d/classCGAL_1_1Aff__transformation__d.html) as the `_` is seen as
subscript operator in LaTeX
## Summary of Changes
Solve a bug for CMap and GMap when we iterate on an empty map with an
iterator that needs to mark cells, and when using index version.
## Release Management
* Affected package(s): CMap GMap
- compare doxygen version with the available directories on disk and
(try to) use the most appropriate one
- give a warning when there are more directories than expected (already
present), though `FATAL` should probably be `FATAL_ERROR` though the
latest will give problems when adding a new version to the directory
list for testing. Changed the message to a `WARNING`
It is not clear to me that this is the right thing to do:
- it is done for some classes
- but in some test, a comment mention that it should be uninitialized
(the test works if init to -1 but not to 0).
- Base_time_stamper is doing an init to -2
## Release Management
* Affected package(s):
* Issue(s) solved (if any): fix#7781#7782
* Feature/Small Feature (if any):
* Link to compiled documentation (obligatory for small feature) [*wrong
link name to be changed*](httpssss://wrong_URL_to_be_changed/Manual/Pkg)

## Summary of Changes
Update our CMake supported versions to ...3.31. That will suppress the
warnings about `CMP0167` (from CMake 3.30):
```
CMake Warning (dev) at cmake/modules/display-third-party-libs-versions.cmake:37 (find_package):
Policy CMP0167 is not set: The FindBoost module is removed. Run "cmake
--help-policy CMP0167" for policy details. Use the cmake_policy command to
set the policy and suppress this warning.
```
## Release Management
* Affected package(s): all cmake scripts
* License and copyright ownership: maintenance by GF
