Thanks, never Cmake here, am trying ../configure --enable-overlayng. I'm <br>
still puzzled about the free output to console not going through the error <br>
or warning handler.<br>

If yes, what is the incantation - I couldn't find any reference to NG in the code or <a href="http://configure.ac" rel="noreferrer" target="_blank">configure.ac</a>?
