I assume you mean you did target_sources(tsc_ui_target INTERFACE dummy.cpp)
target_link_libraries(your_shared_lib PRIVATE tsc_ui_target)
It does work if the direct consumer is a shared lib.
That doesn't quite work if the consuming target is a static lib, that is then
linked into an executable/shared lib.
dummy.o will be archived into the static lib and then discarded when linked
into a shared lib because nothing is referencing symbols from that object file.
Hence the need for object libraries instead of target_sources.. Hence the need
for CMake 3.21.
