Following from the discussion here: http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/3615/focus=5170 (Re: Generator expressisons in target properties, 26 Oct 12:10) we can't split cmTarget API for linking into cmGeneratorTarget. In the future we will probably also need to move the include and compile definitions API back to cmTarget so that it can be used by export().
