That's a nice use case for the new <pkg>_FOUND behavior we've discussed.
The package configuration file would have to cooperate with the cmake-
generated targets file though.  It would have to print a message about
why it sets _FOUND to false.

There has been discussion towards making exports with dependencies
on other exports but no specific proposal has been made.  Mathieu,
the export() command can generate a file in pieces in APPEND mode
but you will loose the verification that all needed targets have
been exported.
