#3793 breaks the CMake build

[alexanderguzhva]

Summary

3793 has incorrect perf_tests/CMakeLists.txt file location. This seems to be a github offloading problem of Phabricator, because I see that the file in a corresponding commit is properly placed

I get the following error after trying to compile current master branch:

CC=clang-18 CXX=clang++-18 cmake -B build_rel -DFAISS_ENABLE_GPU=OFF -DFAISS_ENABLE_PYTHON=OFF -DBUILD_TESTING=ON -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=Release -DFAISS_OPT_LEVEL=avx2 .

Sorry about that, let me look into what's happening. Should be fixed now with https://github.com/facebookresearch/faiss/pull/3885/files merged
