ninja

Guide agents through Ninja as a build executor: diagnosing failures, controlling parallelism, generating from CMake, and understanding the .ninja file format when needed.

The most common use of Ninja is as the build executor for CMake:

| -j N | Parallel jobs (default: CPUs + 2) | | -l N | Don't start new jobs if load average > N | | -k N | Keep going after N failures (default 1) | | -v | Verbose: show full command lines | | -n | Dry run | | -C dir | Change to dir before doing anything | | -t tool | Run a sub-tool (clean, query, targets, graph, compdb) |

忍者构建系统技能。在诊断 Ninja 构建失败、了解 Ninja 作为 CMake 或其他元构建系统生成的低级构建执行器的角色、调整并行性、解释 Ninja 输出或使用 build.ninja 文件时使用。在有关 ninja 错误、ninja 并行性、ninja 详细输出、build.ninja 格式或 ninja 作为 CMake 生成器的查询时激活。 来源：mohitmishra786/low-level-dev-skills。
