I’ve just checked, and you’re completely right - I checked all configurations and there is indeed an order dependency in the Makefile/build.ninja on each source file. I don’t know if my local testing was with some broken version of CMake, but I’ll revert this commit and debug the problem directly if it shows up again. I applied this band-aid because I didn’t think CMake was clever enough to put a dependency on the *source* files - I assumed the dependency was just at the link stage.
