True cross compilation of a ROS package
I have a ROS 2 package from which I can build a .deb for either my native platform, or for another platform by relying on Docker and QEMU. I would like to do a true cross-compile of this package, without relying on QEMU, since the compilation time of this package is a bottleneck in my workflow.
It seems that cross compilation is in a state of flux (https://discourse.ros.org/t/call-for-...). I am looking for recommendations for how to proceed.
For reasons, I am using ROS Eloquent, but I'm hoping any solution is agnostic to the ROS version (so that it works when we use a more modern distro). For concreteness, I've created a minimum example: https://github.com/ggoretkin-bdai/exa...
I can produce both
ros-eloquent-foopkg-msgs_0.0.0-0bionic_amd64.deb
and
ros-eloquent-foopkg-msgs_0.0.0-0bionic_arm64.deb
and I would like to produce the arm64.debmore efficiently by running compilation natively. Ultimately CMake needs a configuration like https://cmake.org/cmake/help/latest/m... .
