+MPF 0.x 有意只安装静态库。共享库需要先明确符号导出、allocator/所有权和版本协商契约；设置 `BUILD_SHARED_LIBS` 不会把当前内部 C++ ABI 意外暴露为受支持的动态库接口。

 The installed package provides the `core`, `javascript`, and `cpp` components; the `mpf::core`, `mpf::backend-javascript`, and `mpf::backend-cpp` targets; and the unified `mpf::mpf` entry point. See [`examples/embedding`](examples/embedding) for a complete integration example.
 
+MPF 0.x installs static libraries deliberately. A supported shared-library ABI will require an explicit symbol-export, allocator/ownership, and version-negotiation contract; setting `BUILD_SHARED_LIBS` does not silently expose the current internal C++ ABI.
