#40648: cmake @2.8.11.2 does not set optimization flags in release

     Type:  defect                |     Status:  new
 Priority:  Normal                |  Milestone:
Component:  ports                 |    Version:
 Keywords:  optimization release  |       Port:  cmake
----------------------------------+--------------------------------
 Recently, projects generated with CMake as installed from MacPorts stopped
 getting optimization flags set in Release mode.

 This appears to be caused by
 https://trac.macports.org/browser/trunk/dports/devel/cmake/Portfile?rev=110069
 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?
