- file(WRITE): add configure_file() decoupling hint

This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.

this wrong behavior. This restores the correct behavior and fixes the
documentation accordingly.
