Hi there,

Thanks for the feedback on this proposal so far. 

I have updated the wiki page to remove any reference to target_use_package() 
or functionality depending on conventions of variable names, or finding 
packages etc. The proposal as written now expects the caller to supply 
targets, and never expects a package name or a prefix.

The page is now focussed on creation of a target_use_targets() command which 
operates on targets which are in scope because either they were created in 
the same buildsystem, or they were imported.

It would be possible to revisit the target_use_package() idea in the future, 
but that is no longer the aim of the proposal. The target_use_targets() is 
already a useful enough concept to aim for.

The remaining (I think) open question regards what form the generator 
expressions should take so that they can represent multiple dimensions.

Thanks,

Steve.
