1. Get spec2000 sources from somewhere

2. create a symlink in this repository root

   ln -s <path-to-downloaded-spec2000-dir>/benchspec
   

3. build benchmarks using --toolchain from wasm_ndk repo

   mkdir build_wasm
   cd build_wasm
   cmake --toolchain $(wasm_ndk_root)/cmake/toolchain/android_wasm.toolchain.cmake ..
   cmake --build .
   

4. build benchmarks for native platform using android toolchain from NDK

   cd build_native
   cmake --toolchain $ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake -DANDROID_ABI=arm64-v8a ..
