when i used system dependencies (2.A) to build LuisaRender and its python binding it have some problem

[HANQAQ]

when i use:cmake -S . -B build -D CMAKE_BUILD_TYPE=Release -D PYTHON_VERSIONS=3.9 -D LUISA_COMPUTE_DOWNLOAD_NVCOMP=ON -D LUISA_COMPUTE_ENABLE_GUI=OFF
it show:--```

-- Configuring done (0.7s)
-- Generating done (0.3s)
-- Build files have been written to: /home/han/Genesis/genesis/ext/LuisaRender/build

then 
i use:`cmake --build build -j $(nproc)`
it show:```

how i solve this problem

It looks like you don't have or have the wrong cuda runtime compilation library

usr/bin/ld: CMakeFiles/luisa-cuda-nvrtc-standalone-compiler.dir/cuda_nvrtc_compiler.cpp.o: in function `main':
cuda_nvrtc_compiler.cpp:(.text.startup+0x173): undefined reference to `nvrtcGetOptiXIRSize'
/usr/bin/ld: cuda_nvrtc_compiler.cpp:(.text.startup+0x197): undefined reference to `nvrtcGetOptiXIR'

Please check the FAQ and see if that fixes the issue.

it maybe i have not OptiX sdk?

To support functions like nvrtcGetOptiXIRSize, you should update your CUDA Toolkit to version 12.0 or higher. The link in the document will be updated soon to NVIDIA's CUDA 12.1.0 download archive.

Additionally, Issues #275 and #194 might be helpful to ensure your CUDA Toolkit is correctly installed.
