On third thought, the tll documentation for the plain signature
does not say it populates the INTERFACE_LINK_LIBRARIES property.
Therefore I think it is okay for the generator expression that
reads it to get an empty value.  If a project wants advanced
use cases like that it should use the tll keyword signatures
or set INTERFACE_LINK_LIBRARIES itself like the tll docs suggest.

Therefore I think the fix as of commit 42a17cc6 is correct
except that it still needs tests for exporting cases.
