+fix Qt macOS build with Clang 18
+
+    See:
+    https://github.com/pnggroup/libpng/commit/893b8113f04d408cc6177c6de19c9889a48faa24.
+
+    In a similar manner as zlib (madler/zlib#895),
+    libpng contains a header configuration that's no longer valid and
+    hasn't been exercised for the macOS target.
+
+    - The target OS conditional macros are misused. Specifically
+      `TARGET_OS_MAC` covers all Apple targets, including iOS, and it
+      should not be checked with `#if defined` as they would always be
+      defined (to either 1 or 0) on Apple platforms.
+    - `#include <fp.h>` no longer works for the macOS target and results
+      in a compilation failure. macOS ships all required functions in
+      `math.h`, and clients should use `math.h` instead.
