+  $1_INDIRECT_EXPORTS := $$(call FindTransitiveIndirectExportsForModules, $$($1_MODULES))

Nit: “exported” term is for API but not for dependency.  

s/$1_INDIRECT_EXPORTS/$1_TRANSITIVE_MODULES
s/FindTransitiveIndirectExportsForModules/FindTransitiveIndirectDepsForModules

Otherwise, looks good.  No need for a new webrev:
