INTERFACE_LINK_LIBRARIES won't work since it won't pull out include path for
dependants.
Using target_link_libraries() on the imported lib does not work because "it is
not built".
So the question remains open : how to represent include and link dependencies
between 2 imported libs ?
With regards,
David
PS : as to why I had to have 2 stages (A_imported and A), this is because I
wanted to add an alias which is not possible on an imported target
