I'm confused on what's going on on the libLAZ repository.
Laszip.hpp is still there and one of the examples [1] relies on it. Weird
that it isn't installed... Looks like the repository is transitioning to
something else, as you pointed out.
Todd, you said Martin wanted to remove the c++ objects. Maybe you can shed
some light on the issue, or else.
I'm at the moment re-considering wether to use pdal or not, given that I'm
only interested in a nice I/O for laz (and las). The LASzipper/LASunzipper
seemed appropriate, but if they are dead... Maybe you all have some
insights about this?
