[pdal] Need help getting started - Can't read compressed file ...

[Adam Steer]

Hi Paul

Install laszip: https://github.com/LASzip/LASzip

 ...or lazperf: https://github.com/hobu/laz-perf

(Are both needed? this I have not tested - but reading laz-perf docs it seems you could get away with just laz-perf, which is a simpler install)

…and then rebuild PDAL

In the ‘scripts’ directory of the PDAL github repo are a load of useful snippets on how to install dependencies and configure builds with optional libraries. I cobbled together my PDAL native build on centOS using bits from the linux-install-scripts and the dockerfile in there.

Happy building!

Adam
