That sounds like 'just' a bug, right? I can't see how that relates to using
set(CMAKE_LINK_INTERFACE_LIBRARIES "")
instead of
macro(wrapper_add_library)
add_library(${ARGN})
target_link_libraries(${ARG1} LINK_INTERFACE_LIBRARIES "")
endmacro()
Then again, I haven't understood your issue, because what I understand from
your issue would make almost the entire exports stuff not work, so clearly I
have not understood your issue.
It looks like it should either be a bug report or a documented limitation
though.
All the best,
Steve.
