Description
I've upgraded to proj 6.0.0 and since then 3.6.2 fails to load any WMS, messagebox shows:
CRITICAL Couche non valide : WMS provider Impossible de calculer l'emprise
on stderr, theres a lot of:
ERROR 1: PROJ: proj_create: Error -9: unknown elliptical parameter name ERROR 1: PROJ: proj_create: Error -9: unknown elliptical parameter name ERROR 1: PROJ: proj_create_from_database: crs not found ERROR 1: PROJ: proj_create: Error -9: unknown elliptical parameter name ERROR 1: PROJ: proj_create: Error -9: unknown elliptical parameter name
it seems the only available proj is 900913, while the server advertises a bunch of EPSG projections.
i can open vector data but i only have "custom" projections.
of course i know proj6 is very new, but cmake machinery is fine building against proj 6, so if it's not supported at all and packagers should stay at proj 5 for now, cmake should complain loudly :)
will try 3.6.3 & proj 6.1.0 but i doubt it'll help, iirc some work was happening in 3.8 for proj 6 support.

Tried readding /usr/local/share/proj/epsg from an older version but that doesnt help.

This is a wontfix.The changes required for proj 6 are too intrusive to allow in 3.6 (or 3.4). Use master/3.8 if you need to build on proj 6.

I was more or less expecting that, but then please dont ignore the issue and at least fix cmake plumbing so that it fails clearly and hard if proj6 is found. That would have prevented me to upgrade proj on my OS.. because all the other consumers have been adapted to build fine with proj6, runtime-issues are tracked/being fixed, but for QGIS it was all silent.
