Not entirely sure, but perhaps this is because (from the macro() docs):
"Note that the parameters to a macro and values such as ARGN are not
variables in the usual CMake sense. They are string replacements much
like the c preprocessor would do with a macro. If you want true CMake
variables you should look at the function command."
