thanks to qiyuxinlin.
your command shows that CUDA compiler was not found. and I solved it by :

export PATH="$PATH:/usr/local/cuda-12.4/bin"
export LD_LIBRARY_PATH="/usr/local/cuda-12.4/lib64:$LD_LIBRARY_PATH"
export LIBRARY_PATH="/usr/local/cuda-12.4/lib64:$LIBRARY_PATH"
export CUDA_PATH="/usr/local/cuda-12.4"

能看到具体的报错，我的报错是因为 thirdparty/llama.cpp 和pybind11 两个文件夹是空的.
解决这两个问题，可以继续往下build 了. Cool
