[Scons-users] scons not respecting variant_dir with object files

[Jason Kenny]

Welcome!

If you have a more project based setup, I think you will find Parts will be useful addition to the build as it tries to make a plugin play like model for components. I have dealt with the need to pull files "outside of tree" in a nice way that should be helpful, as well as rich set of presets to deal with a "build" directories that can be overridden.
