[CMake] organizing export link libraries

Hi all,
a general question:
I have a dependency chain of libraries
A -> B -> C -> ... -> Z
and all of those libraries are built with CMake, using CMake's export
functionality [1] to let the next in the chain know about its the
dependencies.
If all of the libraries are built statically and A needs some symbols
from a third-party library A1, this information needs to travel to Z.
Right now, in the export file I'm writing out the link line as
set(a_EXTRA_LIBS -lhdf5 -lhdf5_hl -ldl -lm -lz -lcurl)
and then in B
set(b_EXTRA_LIBS "<some other libs> -lhdf5 -lhdf5_hl -ldl -lm -lz -lcurl")
and so on.
Is that the preferred way to handle this in CMake? Any other recommendations?
Cheers,
Nico
