Hi Vicky, Regina, Darafei, Daniel,
Thanks for information about CGAL 5.x.
(I just noticed that my macOS homebrew CGAL version is already 5.1...
Also, I misread "focal" as "local", but it was Ubuntu 20.04 LTS version name...)
Definitely, it is quite difficult to install the older CGAL version to newer OS,
so I agree (+1) about the motion, regardless of the related issues
which I mentioned.
Also, about alpha shape implementation itself, I think that it is
worth considering
adding Darafei's proposal to pgRouting 3.x.
Regards,

Yah I think CGAL 5.x switched to header only code. Made me really confused when I first looked at it because I was expecting after a compile I’d have a couple of libraries, but all I got were a bunch of header files so I thought I did something wrong.
SCGAL needed to make a lot of changes to get theirs to work with CGAL 5.x.
SFCGAL head doesn't compile against CGAL 5.1.0beta1 (#234) · Issues · SFCGAL / SFCGAL · GitLab
Moving forward though I think it’s a good thing and now I have no CGAL library dependency anymore when I build SFCGAL.
I suspect they did that so they wouldn’t have packagers screaming at them all the time when they broke a ton of packages because of their changes. Now everything is baked into the applications that they need.

Hello all,
Based on Nagase San comment, I was looking around, and as you can see here:
CGAL 5.6 - Manual: Installing CGAL libraries
CGAL starting from 5.0 works differently of what pgRouting 2.x is configured to work.
I was looking around and starting from focal, CGAL is 5.x
So keep the 2.x series with the new CGAL changes, that might need a lot of work.
Regards

Hi Vicky, list,
The motion itself is okay for me, but about its application timing,
I prefer that after fixing the following 3.x alphaShape issues is better.
- Significant drop in performance when using new pgr_alphashape function · Issue #1345 · pgRouting/pgrouting · GitHub
- pgr_alphaShape sometimes fails (parse error - invalid geometry) · Issue #1603 · pgRouting/pgrouting · GitHub
I will try to check the above issues after next week.
