[QGIS-Developer] Compilation error with 'master'

[pathmapper]

Thanks a lot Jorge Gustavo, yes, I was using PROJ from packages (5.2.0) 
as described in 
https://github.com/qgis/QGIS/blob/master/INSTALL.md#33-install-build-dependencies

Upgrading to Debian testing (bullseye) solved this issue for me.
