Congrats, you've discovered that certain aspects of CMake aren't
actually list oriented.  This is the kind of reason we need Chapter
Oriented documentation, to explain these nuances of lists, strings,
quotes, and escapes.  For compatibility reasons, I don't think
overhauling the string-oriented variables to make them list-oriented
is feasible.  And in one's own code, one has to choose whether to
embrace a string-oriented or list-oriented flag handling style.  More
grist for the chapter.
