     - A compilation option WITH_TP_CACHE is added to cache third-party source codes to avoid repeated downloading. Windows users can set it to ON to speed up compilation and improve compilation stability.
     - The `CUDA_ARCH_NAME` default value is set to `Auto` (`All` indicates compiling all GPU architectures and `Auto` indicates compiling only the current machine GPU architecture). For developers, a lot of compilation time is saved using `Auto` than using `All`, thus improving development efficiency.
     - Redundant links and products and needless file copying are reduced, thus speeding up the compilation in Windows.
