but when use `link_libraries(Botan::Botan gtest)`,is running success，and why ? :

### Additional context

Very confused

Start with botan/CMakeLists.txt and compare the generated link commands for GTest::gtest versus gtest using the provided Fedora, CMake, GCC, and Ninja versions. Reproduce the undefined reference and trace the imported target configuration; done means the cause is identified and the CMake linkage behavior is corrected or clearly documented.
