+Subject: [PATCH] Fallback to elogind when systemd is unavailable at build time
+ https://bugs.webkit.org/show_bug.cgi?id=254475
+
+Reviewed by NOBODY (OOPS!).
+
+The build system supports elogind, but it only considers the
+'libsystemd' library name for the pkg-config lookup and not
+'libelogind'.  This change makes the build system fallback to search
+for libelogind when libsystemd was not found.
+
+* Source/cmake/FindJournald.cmake [!PC_SYSTEMD_FOUND]: Search for libelogind.
