 The cmake based buildsystem for expat works on Windows (cygwin, mingw, Visual

+            #915  CVE-2024-50602 -- Fix crash within function XML_ResumeParser
+                    from a NULL pointer dereference by disallowing function
+                    XML_StopParser to (stop or) suspend an unstarted parser.
+                    A new error code XML_ERROR_NOT_STARTED was introduced to
+                    properly communicate this situation.  // CWE-476 CWE-754

+                    and SOURCE_SUBDIR and its consequences

+### c) The `FetchContent` module
+
+This approach — as demonstrated below — requires CMake >=3.18 for both the
+[`FetchContent` module](https://cmake.org/cmake/help/latest/module/FetchContent.html)
+and its support for the `SOURCE_SUBDIR` option to be available.
+
+Please note that:
+- Use of the `FetchContent` module with *non-release* SHA1s or `master`
+  of libexpat is neither advised nor considered officially supported.
+- Pinning to a specific commit is great for robust CI.
+- Pinning to a specific commit needs updating every time there is a new
+  release of libexpat — either manually or through automation —,
+  to not miss out on libexpat security updates.
+
+For an example that pulls in libexpat via Git:
+
+```cmake

+
+include(FetchContent)
+
+project(hello VERSION 1.0.0)
