pub fn build_env(libtorch: Option<&(PathBuf, String)>) -> Vec<(String, String)>Expand description
The environment a build recipe gets: the same names an fdl.yml
commands.run line already relies on, so a recipe that works there
works here.
What it deliberately does NOT contain is a feature flag fdl chose.
cuda and rocm are this repo’s feature names; a user’s crate pins
its flodl features in its own manifest and may expose neither, so the
vendor is handed over as $FDL_GPU_FEATURE for a recipe to use or
ignore.
