always generate output file even if empty
emaxerrno opened this issue · comments
smfc_generator() cmake function should always generate a file, even if empty.
calling ninja -v -d explain returns the reason why targets are built or not w/ ninja.
If we don't generate the file, the ninja always runs and does unnecessary work which compounds on transitive builds like redpanda to re-build files not needed.

It might be useful to create a special label to track issues that might be worth looking at again in the future. Like this one.
@noahdesu - done. added REVISIT
