[cmake-developers] CMake 2.8.12 transitive link regression?

[Brad King]

Steve,

Likely no one noticed this during the RC cycle because there is no
change in behavior until cmake_minimum_required version is raised
or CMP0022 is set to NEW explicitly.

When CMP0022 is NEW the INTERFACE_LINK_LIBRARIES is always the link
interface without the link implementation fallback, but the tll plain
signature does not populate INTERFACE_LINK_LIBRARIES either.  This is
not correct.

Somehow you'll have to track the tll signatures used in order to
populate INTERFACE_LINK_LIBRARIES properly with the plain signature
if no LINK_INTERFACE_LIBRARIES or keyword signature is used.

We'll need a 2.8.12.1 for this, ASAP.
