I guess 'root' means your source tree right?

Usually you use out-of-source build:
http://www.cmake.org/Wiki/CMake_FAQ#Out-of-source_build_trees

that way the "build" tree (a.k.a: PROJECT_BINARY_DIR)
is separated from "source" tree ((a.k.a: PROJECT_SOURCE_DIR).

That way all generated files goes into the build tree and your source
tree remains "clean", i.e. it only contains "manually" added/modified file.
