> **Note:**
* For RedHat 7.x, please use cmake3(>= 3.15) instead of cmake.
* For debug build, use `-DCMAKE_BUILD_TYPE=Debug -DLLVM_PARALLEL_LINK_JOBS=2` (Linking a debug build of llvm is very memory intensive, so we use only two parallel jobs).
* If you want to build tools (such as [amdllpc](https://github.com/GPUOpen-Drivers/llpc/edit/dev/llpc/docs/amdllpc.md)) together with driver, add `-m build_with_tools.xml` in repo init and add the build option `-DXGK_BUILD_TOOLS=ON`.
