 ## Unreleased
 
+- Added CMake integration through the packaged `UsePRIK.cmake` helper and a
+  `prik generate --cmake` standalone-project mode. CMake generates PRIK wrapper
+  sources as build outputs and owns native compilation, linking, external
+  targets, and incremental rebuilds while preserving per-source flags,
+  compiler-required ABI options, preprocessing dependencies, and linker
+  language from PRIK's completed build plan.
+
+- CMake contract modules now distinguish semantic `NATIVE_LANGUAGE` from the
+  final `LINKER_LANGUAGE`, keep native compilation flags target-local, and
+  report a clear error when CMake's C language is not enabled.
+
+- CMake dependency targets now propagate their native compile usage
+  requirements, and standalone `--cmake --lto` initializes IPO for native and
+  generated targets.
+
+- `prik generate --cmake` keeps each native link input in its own CMake
+  category: prebuilt objects, archives, and shared libraries stay filesystem
+  paths in `LINK_LIBRARIES` instead of becoming ambiguous relative tokens,
+  while library names and linker arguments keep their meaning and order.
+
+- CMake native object targets receive `LINK_LIBRARIES` with the caller's link
+  syntax unchanged, so `debug`/`optimized` keywords and generator-expression
+  entries keep selecting usage requirements per configuration instead of being
+  flattened or dropped.
+
+- CMake mode rejects a `.C` source suffix, which CMake compiles as C++ while
+  PRIK plans the source as C, and reports a clear error when a module
+  contributes native Fortran sources without CMake's Fortran language enabled.
+
+- `prik_add_module()` accepts `LIBRARY_DIRS`, mapping it to
+  `target_link_directories()` and the extension's `BUILD_RPATH`.
+  `generate --cmake` translates `--native-library-dir` into `LIBRARY_DIRS`, so
+  a shared native library outside the system search path is found both at link
+  time and on import without `LD_LIBRARY_PATH`.
+
+- `prik-build.json` schema 5 records generated/native compilation-unit ABI
+  flags and explicit native linker-language requirements.
+
 - Array handles support allocatable and pointer arguments, results, module
   variables, derived fields, optional arguments, and matching ordinary-array
