I think this OUTPUT_PATH property causes cmake to emit two targets that refer to the same file.

Could you re-check with =ninja-1.8.2? This looks similar to https://bugs.gentoo.org/663384.

Could you please test 0.13_rc2

How about 0.13.1?

This has been fixed upstream for quite some time. Also, a change was applied to ninja to fix/workaround the issue on that end.
