There is warning when linking with system google benchmark using CMake. ***WARNING*** Library was built as DEBUG. Timings may be affected. However, when I build benchmark myself using CMake FetchContent, there is no warning. How to reproduce: Setup a CMake project, add any benchmark and link with system google benchmark. And build with Release Build Type. ``` Portage 3.0.66.1 (python 3.12.7-final-0, default/linux/amd64/23.0/desktop/plasma/systemd, gcc-14, glibc-2.40-r5, 6.11.8-gentoo-dist x86_64)

Does the new maintainer really understand this?
I can confirm =dev-cpp/benchmark-1.8.4 works well. And if I append `-DNDEBUG` to CXXFLAGS for =dev-cpp/benchmark-1.9.0, it works well.
