Better than that, it seems to be fixed:

CMake Warning (dev) at CMakeLists.txt:1 (if):
  given arguments:

    "Linux" "matches" "Linux"

  Unknown arguments specified

So I'm happy in that case.  Are there other cases where the error is
not detected?
I think there are -- I've run into once recently -- but I forget what it was.
