Build Acceleration Purpose Guide agents through reducing C/C++ build times using caching (ccache/sccache), distributed compilation (distcc), unity/jumbo builds, precompiled headers, split-DWARF for faster linking, and include pruning with IWYU. Triggers - "My C++ build is too slow — how do I speed it up?" - "How do I set up ccache / sccache?" - "How do precompiled headers work with CMake?" - "How do I set up distributed compilation with distcc?" - "How do I reduce link times with split-DWARF?" - "How do I find which headers are slowing down compilation?" Workflow 1. Diagnose the bottleneck fi…
