- update to 3.23.2:
* The ``CPACK_PACKAGEMAKER_CHOICES`` variable used in the
``CPack.distribution.dist.in`` template file was replaced by a new
``CPACK_APPLE_PKG_INSTALLER_CONTENT`` variable in CMake 3.23.0.
This broke projects that provided their own template file but still
expected the ``CPACK_PACKAGEMAKER_CHOICES`` variable to be defined.
The old ``CPACK_PACKAGEMAKER_CHOICES`` variable is now also set to the
same content as it was before, but it is formally deprecated.

- Edit cmake.macros: Stop injecting -DNDEBUG at the end of
CFLAGS. It's impossible to override by re-setting CFLAGS, and
if it were really wanted globally, it should be in %optflags
instead.
