Starting with CUDA 10.2 the nvcc compiler has gained support to automatically forward unknown flags to the host compiler. This behavior is highly desired as projcts that mix CUDA, C, C++ run into situation where flags such as `-pthread` which aren't supported by nvcc, are being applied to all source files and therefore break CUDA compilation.
