Note that the existing periodic triangulations are compatible with CGAL's alpha shapes, see https://doc.cgal.org/latest/Alpha_shapes_2/Alpha_shapes_2_2ex_periodic_alpha_shapes_2_8cpp-example.html / https://doc.cgal.org/latest/Alpha_shapes_3/Alpha_shapes_3_2ex_periodic_alpha_shapes_3_8cpp-example.html. Do you have any specific requests on the periodic packages while I am working...

I didn't notice any slow down in compilation/runtime when using `Filtered_predicate_RT_FT` for predicates that are FT-only (I ran a large compilation and execution of `Compare_distance_2`). [Here](https://gist.github.com/MaelRL/2332e0ff4d2d29231f3ccb845cd53181) is a log of...

I have one issue left, related to templated operators, e.g. `Do_intersect_2`: with some arguments, it might be `RT_sufficient` while with some others, it might need `FT_necessary`. As such, whichever tag...

[Here](https://gist.github.com/MaelRL/d6976402cb2fe94fc1311768b24436f2) is the log for the new test. There are a couple of errors, but it's expected: they are all within templated `operator()`s, where some combinations are RT-sufficient, and some...

@lrineau Could you please clarify what's the best practice for `PRIVATE`/`PUBLIC` on linking / compilation macros definition? Reading https://cmake.org/pipermail/cmake/2016-May/063400.html, I don't understand why some 3rd party such as `TBB`, `METIS`,...

Some missing "missing 3rd party dependencies" messages have been added (e.g. [in T3](https://github.com/CGAL/cgal/pull/6835/files#diff-58654bf1f3290bb236c6d31ec93d008ff45785b9fd821e31c98d03831f0accaaR29)), so this is expected, but I will check them individually.

> Hi team, > > is there any plan for the second item of the TODO " duplicate_non_manifold_edges_in_polygon_soup into repair_manifoldness.h?" ? This is just moving an existing function, which you...

As the name/API indicate, it is meant to work on a polygon soup, but you can convert from and to a polygon mesh with [polygon_mesh_to_polygon_soup](https://doc.cgal.org/latest/Polygon_mesh_processing/group__PMP__repairing__grp.html#ga3be94f1f7968022a294dd533400ad554) / [polygon_soup_to_polygon_mesh](https://doc.cgal.org/latest/Polygon_mesh_processing/group__PMP__repairing__grp.html#ga2ba9722ec8472a1455107ffce7145e46) (or [read the...

Also as a temporary fix, could this define a filtered Compare_distance_3 predicate as it would be in the macro, but using the RT kernel? Since you know that the overload...

[Here](https://gist.github.com/MaelRL/3f8ba9f286090820109c3e4e0e7eb73d) is some proof of concept code to test automatically, based on parsing the compilation log (I got the same idea as Marc to handle ambiguity). It contains only a...
