You can add `-GNinja` to `cmake` above to use Ninja build system (invoke build using `ninja` or `cmake --build .`).

For Rasberry Pi 3, add `-DCMAKE_TOOLCHAIN_FILE=../toolchains/pi3.toolchain.cmake -DPI3=ON` to cmake. You can also consider disabling Vulkan support as the Vulkan drivers for Rasberry Pi are still not mature, but it doesn't hurt to build the support in, but not use it.

Open ```$RISCV_ROOT_PATH/lib/gcc/riscv64-unknown-linux-gnu/10.2.0/include/riscv_vector.h```, goto the file end, you will find three ```#endif```, and apply changes as the following
