Compiling cuda on Windows

Hi, I’m new here.

Clang wrote that it supports compiling cuda on Windows
http://llvm.org/docs/CompileCudaWithLLVM.html

The page says to compile with two specific linker flags “-ldl -lrt”, which my linker fails to find, and after searching my entire cuda directory manually, still failed to find. (-lcudart-static is fine)

Is this clang’s problem or is this cuda’s problem?
