[QGIS-Developer] QGIS build error in Ubuntu 18.04

[Stephen Knox]

Hi Samweli,

I had the same issue. I was also using PROJ 7, and getting an identical
error. It looks like this issue might be related to this one:
https://github.com/qgis/QGIS/issues/35195, so this looks unlikely to be an
isolated issue.

I was able to resolve by downgrading to PROJ 6.3.1, but clearly that isn't
a long-term solution. I'm not clear whether this is related to Proj 7
itself or the way that QGIS is using it.
