You CANNOT use CPACK_SET_DESTDIR safely on Windows.
You'll get a warning message in 2.8.9 and I personnally think that
this should became an error sooner or later.

Using CPACK_SET_DESTDIR with NSIS is usually a mistake
or a misunderstanding.

What is the goal of your usage of CPACK_SET_DESTDIR with NSIS in the
first place?

Setting CPACK_SET_DESTDIR to ON 'manually'
is seldom needed and is now handled internally & automatically by some
generators for necessary
case like installing absolute destination file with RPM or DEB.
