Handle targets in the LINK_LIBRARIES of try_compile.
Imported targets are re-exported so that they can be used by the try_compile generated code with target_link_libraries. This makes the use of the cmake_expand_imported_targets macro obsolete. The macro is not able to expand the generator expressions which may appear in the IMPORTED_LINK_INTERFACE_LIBRARIES content. Instead it just sees them as 'not a target'.
