+Subject: [PATCH] tests: allow using system gtest copy
+
+Distributions often do builds with no network access available
+for both security reasons and also to ensure reproducibility.
+
+This change tells CMake to query the system for a copy of gtest,
+but if it's not available, it'll fall back to downloading via
+FetchContent.
