TODO: document that the "last" version of LASTools is required, and precise since which version it will work.

[sloriot]

This PR makes the LASTools distributed by CGAL incompatible with CGAL-6.0 (see here for example). Any chance to fix that ? The reason why it would be nice to have is that we would install a single version on test platforms and it would work both with master and the release branches.

Actually, if this PR target 5.5.x-branch then we would be good with test platforms being updated.
