[CMake] cmake project patterns / examples

[Chuck Atkins]

"Just put all the build commands in the top level cmake file."

Definitely an anti-pattern.  As you mentioned, it definitely doesn't
scale.  The problem with even doing this for a simple project is that it
builds this behavior for people trying to learn cmake through simple
examples.  This very very quickly turns in to a 3k line top level
CMakeLists.txt  for even moderately sized projects.  I would really
discourage this one as "don't do it ever" because of the bad behaviours it
builds early on.
