When I followed instructions in the documentation, to build humble ros2 from source in ubuntu 20.04, the build folder turned out to be quite large, which is over 11G. And I noticed the size of humble is much smaller if installed from binary.

I want to decrease the size of humble folder, and there is a Jenkins BUILD_URL in released tar file in github. Is there any way to build humble source using the same Jenkins or other CI?

github tar file link: https://github.com/ros2/ros2/releases/download/release-humble-20230614/ros2-humble-20230614-linux-jammy-amd64.tar.bz2

BUILDURL: https://ci.ros2.org/job/packaginglinux/3063/
