Speeds up CMake run significantly and reduces Conan output a lot.

Helps to identify that not everything was built. Prevents empty
artifacts when browsing to
https://jenkins.opengeosys.org/job/ufz/job/ogs/job/master/lastSuccessfulBuild/artifact/

Jenkins link should update on each build but somehow netlify does
not invalidate the cache for it... Only manually deleting the cache
worked so I temporarily set
https://jenkins.opengeosys.org/job/ufz/job/ogs/job/master/lastSuccessfulBuild/artifact/
as the download link.
