Reproduction instructions

The build and library installation commands are shown below.

# Install command
cmake . \
    -B build \
    -DFAISS_ENABLE_GPU=ON \
    -DFAISS_ENABLE_PYTHON=OFF \
    -DBUILD_TESTING=OFF \
    -DFAISS_OPT_LEVEL="generic" \
    -DCMAKE_BUILD_TYPE=Release && \
cmake --build build --config Release -j3 && \
cmake --install build

After executing the command, I check /usr/local/lib and /usr/local/lib64 and libfaiss_gpu.a is not copied.

ls /usr/local/lib | grep libfaiss_gpu.a
ls /usr/local/lib64 | grep libfaiss_gpu.a

The objective was to merge the object files from libfaiss_gpu.a entirely into libfaiss*
