Make the existing
LLVM_USE_CRT_<CONFIG>settings control the MSBuild runtime-library property generated by modern CMake, and add the initial cache composition point for official Release policy.CMake's
CMP0091runtime-library abstraction emits<RuntimeLibrary>in Visual Studio projects. The currentChooseMSVCCRT.cmakeimplementation instead editsCMAKE_<LANG>_FLAGS_<CONFIG>, which can leave an explicit/MTcompeting with CMake's generated/MDselection. Translate the existingMD,MDd,MT, andMTdvalues toCMAKE_MSVC_RUNTIME_LIBRARYso the requested runtime is authoritative. Configurations without an explicit override retain CMake's normal DLL-runtime defaults.cmake/caches/OfficialRelease.cmakecurrently composesPredefinedParams.cmakeand selectsLLVM_USE_CRT_RELEASE=MT. This is intentionally an initial, narrow cache rather than a claim that all DXCBuild release policy has moved upstream. It does not configure versioning, signing, symbol packaging, artifact publication, or size-first optimization policy. Additional generally useful release settings can move upstream independently before the cache is documented as reproducing the complete compiler configuration used by DXCBuild.Testing:
OfficialRelease.cmakefor CRT selection.<RuntimeLibrary>MultiThreaded</RuntimeLibrary>for Release andMultiThreadedDebugDLLfor Debug. The only projects without runtime properties were CMake's two configure-time compiler-identification probes.llvm-tblgentarget successfully through the official cache.dumpbin /dependentsreports onlyKERNEL32.dll, with noVCRUNTIME,MSVCP, UCRT, or API-set CRT imports.No release note is needed because this changes build-system behavior rather than compiler-visible behavior.
