Hi James,

Not sure if it is comparable with your setup, but I was just able to
compile QGIS with GDAL 3.0.0 with Proj 6.0.0 on Debian testing, by doing
this 'renaming' trick:

https://trac.osgeo.org/gdal/wiki/BuildingOnUnixGDAL25dev

checking if libgdal.so was indeed linked to libinternalproj.

and then ( as Even proposed in
https://lists.osgeo.org/pipermail/qgis-developer/2019-May/057309.html )
using -DCMAKE_CXX_FLAGS=-DPROJ_RENAME_SYMBOLS in the ccmake of QGIS

( but as said, maybe your setup is more complex, and I understand just
half what I'm doing :-) )

Regards,

Richard Duivenvoorde
