I will 'fess up here.  :-) I have never used <PROJECT_NAME>_SOURCE_DIR and
<PROJECT_NAME>_BINARY_DIR but they are well documented so I should have
easily found them but didn't.  My problem was I was looking for an exact
match of MAIN_BINARY_DIR and MAIN_SOURCE_DIR (Alexander's project name was
MAIN), but you should never try exact matches.  Live and learn.
