[CMake] INSTALL DIRECTORY patterns highly confusing

[Dan Kegel]

Of course.  The problem comes when somebody is used to languages that
encourage single-quoted strings (e.g. python or shell) or which have tight
syntax and abort on mistakes like this.

This lack of early feedback coupled with the terse doc and strange
semantics means that when something doesn't work, the user has a hard time
figuring out what kind of mistake he made.
