During building my ROS project using catkin build, I often times see deprecation warnings popping up which I deem useless information. This deprecation warnings are coming from my code and also it's dependencies (eg:Googletest, catkin_tools_prebuild)
I would like to suppress these deprecation warnings. After doing some research, it seems like I have to set CMAKE_WARN_DEPRECATED to False. How do I set this variable in ROS?
What I found to work best in suppressing the deprecation warnings of all packages, including yours and it's dependencies, is to set the CMAKE_WARN_DEPRECATED in catkin config before doing catkin build.
In the catkin environment:
catkin config --cmake-args -DCMAKE_WARN_DEPRECATED=OFF
