  ## Additional Information

  * Dependent on https://github.com/dashpay/dash/pull/6384
  * Dependency for https://github.com/dashpay/dash/pull/6389
  * The Qt patch introduced in [dash#5596](https://github.com/dashpay/dash/pull/5596), `fix_qt_placeholders.patch`, was a portion of a suggested workaround for QTBUG-92199 ([source](https://bugreports.qt.io/browse/QTBUG-92199?focusedId=669719&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-669719)) but since then, a fix ([here](https://codereview.qt-project.org/c/qt/qtbase/+/434310)) has made its way to 5.15.12 and we are upgrading to 5.15.14 from 5.15.11.

    So we can safely remove this patch.

+
+    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+    libpng contains a header configuration that's no longer valid and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.
