[gdal-dev] Compile problems gdal3.0.2 against proj6

[Even Rouault]

GDAL build system doesn't use rpath mechanism for linking, so if there are 
several libproj.so in the path used for linking it will use the first or last 
one, I never remember :-).
Anyway, even if you manage to build, you're bound to run into runtime problems 
if you intend to link GDAL against PROJ 6 and spatialite built against an 
older PROJ.

So 2 ways:
- uninstall the proj development package, and build spatialite against proj6 
too
- or use the trick at https://trac.osgeo.org/gdal/wiki/BuildingOnUnixGDAL25dev
