+# =============================================================================
+# Cesium for Unreal — Custom Abseil overlay port
+# =============================================================================
+#
+# This overlay customizes the standard vcpkg abseil port in several ways
+# required for compatibility with Unreal Engine. When upgrading the abseil
+# version, re-apply each customization described below and verify it is still
+# necessary.
+#
+# CUSTOMIZATION HISTORY:
+#   Originally created Nov 2024 (abseil 20240722.0) to fix Android and MSVC
+#   build issues. Updated to 20260107.1 to match the vcpkg 2026.04.27 baseline.
+#
+# BACKGROUND — Unreal Engine and the Android NDK:
+#   Unreal Engine uses C++20. However, the Android NDK version bundled with
+#   Unreal has incomplete C++20 *library* support even though the compiler
+#   supports C++20 *language* features. This means headers that are compiled
+#   as part of Unreal's Android build (including installed vcpkg headers) must
+#   not rely on C++20 standard library types such as std::partial_ordering.
+#   We build abseil itself with C++17 to avoid any C++20 library dependencies
+#   in abseil's own compilation. We additionally patch the installed headers
+#   to be safe when included by Unreal's C++20 Android build.

+# cord.h guards C++20 comparison code with __cpp_impl_three_way_comparison,
+# which causes a build failure on NDK r25 when the library support is missing.
+# We replace the guard with the library feature macro, which is the correct
+# check. See: https://github.com/abseil/abseil-cpp/pull/1728
