So, what happens if you try to collect all the .cmi dependencies and 
then replace the suffixes to .cmo? This would probably require a custom 
.SCANNER rule to produce the dependencies, but such rule should be easy 
to write - you could make the original .cmo the dependency of the 
.SCANNER rule, so the rule would only have, again, to ask for all the 
.cmi dependencies of the original .cmo and replace the suffixes - so you 
should be able to write it with just a few lines of OMake code.
