[QGIS-Developer] WinGRASS build up (WIP)

[Helmut Kudrnovsky]

>Any idea when GRASS will be updated with the new dependencies?

see https://github.com/OSGeo/grass/pull/136#issuecomment-547497328

"Sure it is still GDAL2"

is OSGeo4W still default in gdal2/proj5? is gdal3/proj6 still in OSGeo4W experimental/testing?

in #136, environment is pointing to gdal-dev proj-dev, which I assume is gdal3/proj6, right?

GRASS is in a RC cycle for GRASS 7.8.1: RC1

a possible workflow may be (?):

(1) update/adapt #136 to reflect a default gdal3/proj6 in OSGeo4W
(2) apply updated PR to issue a GRASS 7.8.1 RC2
(3) switch OSGeo4W to a default gdal3/proj6
(4) binary release GRASS 7.8.1 RC2 in OSGeo4W

@Martin: any opinion?

Kind regards
Helmut
