[gdal-dev] GDAL 2.0.2 doesn't compile with Kakadu 7.7.1

[Andre Hollstein]

Dear Even,

thanks for pointing me to https://trac.osgeo.org/gdal/changeset/31517, I 
will use this. Maybe it would help to avoid confusion to reflect the 
need to set
CXXFLAGS="-DKDU_MAJOR_VERSION=7 -DKDU_MINOR_VERSION=7 in the ./configure 
--help message. I was missing this info.

Thanks a lot again,

André
