[Bug]: "multiple rules generate" with Ninja Multiconfig in CROSS_CONFIG mode

[xTachyon]

Current Behavior

Building a simple project which imports a rust static lib fails to build when invoking ninja.

Expected Behavior

The build works.

Steps To Reproduce

> cmake .. -G "Ninja Multi-Config" -DCMAKE_CROSS_CONFIGS="Debug;Release" -DCMAKE_DEFAULT_CONFIGS="Debug;Release"

> ninja
ninja: error: CMakeFiles/impl-Debug.ninja:122: multiple rules generate libthe_rust_lib.a

Environment

- OS: Ubuntu 23.10
- CMake: 3.27.4
- CMake Generator: Ninja Multi-Config
