QGIS isn't built with PDAL

[mapperfr]

What is the bug or the crash?

Can't open LAZ files with QGIS.

Steps to reproduce the issue

1. Drag and drop a .laz file (this one was coming from IGN's LidarHD. Click here to download one of the files I tried to open). Alternatively, go to "Layer > Add layer > Add point cloud layer" and select the file.
2. The following error message opens:

fr

"Les fichiers LAS et LAZ ne peuvent pas être ouverts par cette version de QGIS.
Cette version de QGIS ne contient pas la librairie PDAL nécessaire pour ouvrir les nuages de points LAS ou LAZ."

en

"LAS and LAZ files cannot be opened with this version of QGIS.
This version of QGIS does not contain the PDAL library required to open LAS or LAZ point clouds."

Not a qgis issue -- Ubuntu doesn't provide the required libraries for point cloud support anymore (pdal). There's nothing qgis can do about this.

Oh :/
Thanks for the details Nyall.
Do you think it's a dead-end for now or there's a chance to get it supported again?
If you know the door I should knock on about that I'd be happy to do so.

As a workaround, I installed pdal via conda and converted my laz files to copc. I could then open and process the .copc.laz files with no issues.

Please note that if you use QGIS packages based on Ubuntugis, PDAL support will be included, because the Ubuntugis repository contains PDAL packages as well.
