Summary
New macro/rule parameter
output_dir(default""== workspace root, matching the historical behaviour). When set, both the pre-write unlink and theopen()target are rerouted to<output_dir>/compile_commands.json.Useful when you want
compile_commands.jsonin a subdirectory (e.g.build/) rather than the workspace root.Upstream context
Backport of hedronvision#210 (ilev4ik), adapted to coexist with our backport of #193: the unlink-before-write call also honours
output_dir.Test plan
output_dir = "build": file lands inbuild/compile_commands.json
