cmake @2.8.11.2 does not set optimization flags in release

[macports@…]

Recently, projects generated with CMake as installed from MacPorts stopped getting optimization flags set in Release mode.

This appears to be caused by r110069 wherein the Portfile was configured to explicitly strip -O3 from the compiler modules shipped with CMake.

While it may well be true that when CMake is used to generate makefiles for a port, one should not set an optimization flag (I don't know), it does not seem to be the correct behavior for any non-MacPorts project that is using CMake installed by MacPorts. This seems to me to be a pretty standard use case- it's certainly what my team has been doing. This change makes it impossible to make a release build of software without additional hackery to force the optimization flag back in.

I'm not sure what the correct solution is. I'm hoping someone with a deeper knowledge has some ideas?
