@ben.boeckel Can you suggest some improved wording for the $<TARGET_NAME:...> generator expression documentation? It currently says “This is required if exporting targets to multiple dependent export sets”, but it doesn’t say why. Some sort of example would really help, but I don’t really understand the use of this even after looking at its C++ implementation (which does nothing but unconditionally return the target name anyway, so I don’t know what it is affecting). Having arrived here myself after another export-related problem in a different project but with similar error message, it is apparent that we need to make it clearer what problems $<TARGET_NAME:...> does and does not solve.
