Yes, it's also the one that started this thread.  Do we agree that
full generate-time evaluation is appropriate for these?  If so then
the implementation will require BUILD_TYPE conditional blocks in
generated cmake_install.cmake files.

Yes, definately.

Are you proposing this for inclusion in 2.8.12?  IMO it can
wait along with the rest.

I forgot, which config-related generator expressions on imported
targets honor MAP_IMPORTED_CONFIG_<CONFIG>?

What is the behavior when a not-allowed expression like
STREQUAL is used?  Does it produce an error message?
