cgal: add cgal/6.0

[lrineau]

Summary

Changes to recipe: cgal/6.0

Resolves #25050.

Motivation

New upstream release: CGAL version 6.0, https://github.com/CGAL/cgal/releases/tag/v6.0

Details

CGAL 6.0 has a few breaking changes. The major one is that C++17 or later is now required (instead of C++14 for version 5.6).

Also: the PR CGAL/cgal#7512 is merged in CGAL-6.0. That changes the creation of the file lib/cmake/CGAL/conan-official-cgal-variables.cmake, that is now simpler:

include(${CMAKE_CURRENT_LIST_DIR}/CGAL_SetupCGALDependencies.cmake)
CGAL_setup_CGAL_flags(CGAL::CGAL)

# CGAL use may rely on the presence of those two variables
set(CGAL_USE_GMP  TRUE CACHE INTERNAL "CGAL library is configured to use GMP")
set(CGAL_USE_MPFR TRUE CACHE INTERNAL "CGAL library is configured to use MPFR")

Hi @AbrilRBS. Let me know if there is anything I should do about this PR. I am unsure about the PR #25050, that adds cgal/6.0-beta1. This one is about cgal/6.0, the official release.

[AbrilRBS]

Thanks a lot! We appreciate you taking the time to create the PR for the new release :)
