This PR proposes an edit to allow building dune projects with
generate_sites_module
stanza, even whenimplicit_transitive_deps
is set to false, which is the desired behavior.In short, when using
genereate_sites_modules
, the modulesites.ml
is generated havingdune-site
library as a direct dependency, which in turn hasdune-section
private library as a transitive dep. Sincedune-section
is used explicitly insites.ml
, the build fails whenimplicit_transitive_deps
is set to false (even with dune supporting hidden deps, see #10644).Therefore, dune-section is re_exported in the stanza of dune-site in order to avoid this failure.
Fixes #9661
