Fixes building for Windows x86 with MSVC using the link libraries distributed with the CUDA SDK.

check_lib2 is required here because it includes the header to get the full signature of the
function, including the stdcall calling convention and all of its arguments, which enables
the linker to determine the fully qualified object name and resolve it through the import
library, since the CUDA SDK libraries do not include un-qualified aliases.
