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

• Potentially malicious external URL detected (high risk: 0.70). The CMake snippet uses FetchContent_Declare to download and build GoogleTest from https://github.com/google/googletest/archive/refs/tags/${GTEST_VERSION}.zip at build/runtime, which fetches and causes external code to be compiled/executed as a required dependency.
