Hi Even,
Thank you for your help!
I went with the 4.3.0a version and the CFLAGS telling it to use the old
API version.
That seems to compile fine. Fingers crossed that gdal and QGIS also like
this approach.
Thanks again,
Andreas

For 4.3.0a:
CFLAGS="-DACCEPT_USE_OF_DEPRECATED_PROJ_API_H -O2 should help:

You can also build against the development repository of Spatialite:
https://github.com/OSGeo/gdal/blob/master/gdal/ci/travis/ubuntu_1804/install.sh#L27
(you could probably drop the "fossil update 90180e065d" which must
have been a
workaround against a regression, and the other peculiarities), so mostly:
fossil clone https://www.gaia-gis.it/fossil/libspatialite
libspatialite.fossil
mkdir sl
cd sl
fossil open ../libspatialite.fossil
./configure [...]

Yes, I've tried to maintain a communication channel with the
developper, but with
moderate success only. The development is not abandoned, but only at a
rather slow
pace.

I don't think you can without some surgery in the code base.
FWIW, the WFS provider depends on it for caching (could potentially be
replaced by
something else)
