I like to run the llvm-test-suite with other compilers as well such as
gcc. It requires LIT, but that can be installed separately
(https://pypi.org/project/lit/). I would already satisfied if there
there is a possibility to use alternative sources of google benchmark,
such as installed by the disto package manager (sudo apt install
libbenchmark1) or automatically downloaded using CMake:

include(FetchContent)
FetchContent_Declare(googlebenchmark
    GIT_REPOSITORY https://github.com/google/benchmark.git
)
FetchContent_MakeAvailable(googlebenchmark)
