[QGIS-Developer] not building against pdal 2.4.0rc1

[Martin Dobias]

Hi

Thanks for reporting the compilation issue with PDAL 2.4.0. RC1. I have
reported the issue to the PDAL developers and they have already prepared a
fix: https://github.com/PDAL/PDAL/pull/3713 - I am hoping it will land in
the final 2.4.0 release.

Regards
Martin
