Yes, although the error message is triggered when it finds specific
files inside the tree, even if you actually call cmake from outside the
tree. So if you do an in-tree build first, then realize your error, and
try the out-of-tree build afterwards, you still see the same error.

OK, that's unusual and I can't reproduce it here even by copy & pasting
the commands and doing exactly the same. You could try 3.7.2.1 (although
I couldn't say why 3.7.2 wouldn't work) and using other build
directories.
