Research direction

Start by reproducing the configuration with CMake’s Ninja generator, then inspect the build rules that generate moonray/moonray/dso/camera/BakeCamera/BakeCamera.json. Find where that output is declared more than once and compare the Ninja build setup with the working Makefile setup. Done when the Ninja configuration completes without the duplicate-rule error.

Description

I have been able to compile OpenMoonRay via Makefile

I am also trying to build it via Ninja

However, I am getting the following configuration error when running cmake with the Ninja generator

-- Configuring done (2.2s)
CMake Error:
  Running

   '/usr/bin/ninja' '-C' '/home/nyue/projects/OpenMoonRay/head/build' '-t' 'recompact'

  failed with:

   ninja: error: build.ninja:17682: multiple rules generate moonray/moonray/dso/camera/BakeCamera/BakeCamera.json [-w dupbuild=err]
