Changing orocos-rtt.default.cmake is not recommended, since the file itself
says that you must copy it to orocos-rtt.cmake and edit that file. It will only
influence the RTT itself.
For setting it for all other packages (including OCL), create a rosconfig.cmake
file in the ROS_ROOT directory, and set the build type there, see the
documentation here:

In ROS builds, a make clean will wipe your build dir, and the files in lib/ and
bin/, while doing a rm -rf build, will leave the files in lib/ and bin/
untouched. So you want the latter.
