I am not using Xcode myself but a very brief look into the
cmake source reveals that the variable

CMAKE_CONFIGURATION_TYPES

is used instead of CMAKE_BUILD_TYPE. Now the default value for 
CMAKE_CONFIGURATION_TYPES is  "Debug;Release;MinSizeRel;RelWithDebInfo".

Simply setting CMAKE_CONFIGURATION_TYPES to

 "Release;Debug;MinSizeRel;RelWithDebInfo"

was sufficient to convince Xcode to build 
with release instead of Debug mode by default.

I would suggest to change this order in cmake
because having debug as default in a software 
distribution seems not so appropriate given that you
cannot assume that all people that may download 
and compile  your software with Xcode are
really knowing what they are doing.

As suggested by Gonzalo the same change of order may
be a simple solution for other IDE's as well.
