[CMake] Force copy of files

[David Cole]

"copy" should always overwrite.

"copy_if_different" will conditionally overwrite, only if the contents
of the two files are different.

If "copy" was not overwriting something when it should have been,
please send steps to reproduce the issue, because that would be a bug.


HTH,
David C.
