cmNinjaTargetGenerator: ensure that the object output directory exists (!9105) · Merge requests · CMake / CMake

Ben Boeckel requested to merge ben.boeckel/cmake:ninja-always-make-object-dirs into master Dec 26, 2023

If a target has no object compilations within it, nothing ensures that the directory exists yet it is still mentioned as an order-only dependency within the build files. While ninja is OK with this, samu, an alternate ninja implementation, is not. Make sure the directory always exists for consistency.

Also add a test case.

Fixes: #25526 (closed)

Maybe fine for %3.28.2?
