xmake will detect cuda sdk environment automatically, we can only run the following command to compile cuda program:

$ xmake

And we can also configure a given cuda sdk directory if detect failed.

$ xmake f --cuda=/usr/local/cuda-9.1/ 
$ xmake

Create an empty project for cuda:

$ xmake create -P test -l cuda
$ cd test
