The new vcpkg baseline includes abseil 20260107.1 (up from 20240722.0). s2geometry now requires absl::byteswap which is present in the new abseil but was missing from the old version, so this upgrade is necessary. All Unreal-specific customizations are preserved and documented in the portfile. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
…nts. - Change CMAKE_CXX_STANDARD from 14 to 17. Abseil 20260107.1 requires C++17 minimum. The original C++14 setting was incorrect - Unreal uses C++20, not C++14. C++17 is the right build standard: it avoids C++20 library dependencies that are missing from Unreal's Android NDK while still satisfying abseil's own minimum requirement. - Restore the cord.h Android NDK r25 fix that was accidentally dropped. Even though we build abseil with C++17, Unreal's C++20 build includes the installed cord.h header and hits the same issue. - Update all comments to accurately describe the constraint: Unreal uses C++20, but its Android NDK has incomplete C++20 library support.

Synced with the upstream vcpkg port for this version. New features (dbpage-vtab, snapshot, unicode/ICU) are included. The Cesium-specific symbol renaming (sqlite3 -> cesium_sqlite3) is preserved to avoid linker conflicts with Unreal Engine's bundled sqlite3.

…L_CONFIGURE from abseil. The add-config-include.patch was originally copied from vcpkg 2024.02.14 and had context lines from an older SQLite version. The patch failed to apply against SQLite 3.53.0 because the surrounding code structure changed (the old version lacked the '#ifndef SQLITE_AMALGAMATION' guard). Update the context lines to match 3.53.0, taken directly from the upstream vcpkg port at 56bb2411. Also remove DISABLE_PARALLEL_CONFIGURE from the abseil portfile. It was carried over from the old overlay but the upstream vcpkg port removed it, and there is no evidence it is needed for Unreal specifically.

- abseil/portfile.cmake: restore upstream MINGW comments that were
accidentally dropped, add back ${ABSL_TEST_HELPERS_OPTIONS}, match
upstream line ordering in vcpkg_cmake_configure.
- sqlite3/add-config-include.patch: copy directly from upstream (now
identical, no reason to differ).
- sqlite3/sqlite3-config.in.cmake: copy directly from upstream (was
whitespace-only different).
- sqlite3/sqlite3.pc.in: copy directly from upstream (was missing the
Requires.private line for no reason).

It looks like it shouldn't be needed anymore.

This depends on CesiumGS/cesium-native#1360 so merge that first.
