I don't know what you mean by 'persist'.

The new documentation in CMake 3.0 also apply to earlier versions,
insofar as the properties and commands exist:


target properties are /Usage Requirements/ – they specify content which
consumers must use to correctly compile and link with the target they
appear on. For any binary target, the contents of each INTERFACE_
property on each target specified in a target_link_libraries()
command is consumed"

So, further user action is not necessary beyond use of
target_link_libraries, if the targets have such properties populated.

Some information in


might also be useful to you.
