01 / FAILURE SIGNATURE

As reported upstream

ninja: error: build.ninja:388: multiple rules generate libpugixml.a [-w dupbuild=err]

Not a benchmark task.

The project already builds and runs before the fix, so there is nothing to repair.

This is with CMake 3.17.1 and Ninja 1.10.0 and happens since https://github.com/zeux/pugixml/commit/2c24e90c238e5142edb389c2a9735a9c1bae9039.



I think it isn't save to have to targets with the same name?
