Isn't there an example in the cmake book about this where you have to
have \\\\ (four backslashes) to survive all the escaping that happens
downstream?

Anyway, to paraphrase a quote I see on slashdot all the time,
backslashes are like violence: if they don't work, apply more. Does it
work if you use \\\\$PPROJECT_NAME}.exe?
