There are two cases: 1) the library just passes things through A gtk structure could have a "struct atk *" member that is passed down to libatk by the application without gtk ever touching it. In that case the binary should be linked against gtk and atk but libgtk should not link against atk. A change in the struct atk would not affect libgtk. 2) the library uses and exports part of the other lib Again say a gtk structure has a "struct atk *" as member but gtk also dereferences the pointer and uses the contents. In that case libgtk should link against atk itself already. A change in the structure would affect libgtk. The (useless) linking to atk would show the dependency on the ABI. In both cases the CFLAGS would have to include the atk include path though. > What we need is an option follow requires for cflags but not for libs. > > Hopefully, one day....
