Right.  And because with autotools, the build process works as well in
the source tree, in a build subdirectory, or completely separate build
directory, no particular approach is preferred over another.

If CMake recommends one approach (or avoiding another), this implies it
doesn't work well (or as well) with that approach because of
shortcomings in the tool rather than "it's good development practice". 
Or maybe its both?
