Great!  I've applied the patch with a few tweaks:

 cmake: Add -W options to control deprecation warnings and errors
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=c96fe0b4

The largest change is that I hid CMAKE_SUPPRESS_DEVELOPER_ERRORS
from public documentation since it is just an implementation
detail to store the corresponding options persistently.

Thanks,
