How can I add C++ optimization flags to ROS
I am running an opencv code on ROS and I really need to turn on the -O3 optimization flag.

I am running an opencv code on ROS and I really need to turn on the -O3 optimization flag.
Call catkin_make -DCMAKE_BUILD_TYPE=Release
to turn on the default optimization flags for release builds. -O3
should be in there, as far as I know.
Otherwise, you can add compile flags on a per node basis by specifying set_target_properties(<TARGET> PROPERTIES COMPILE_FLAGS "-O3")
in the CMakeLists.txt
. However, I'm not sure how this is handled then in combination with a build type.
thank you very much. I just typed in catkin_make -DCMAKE_BUILD_TYPE=Release and it worked fine thanks.
