MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The CMake snippet uses FetchContent to download googletest from https://github.com/google/googletest/archive/refs/tags/${GTEST_VERSION}.zip at configure/build time, which fetches remote code that will be compiled/executed and is treated as a required dependency.
