#Goal for this example:
#Verify that when we have CXX and CUDA enabled and we link an executable that
#has CUDA and CXX we use the CUDA link flags when doing the device link
#step
#Specify a set of valid CUDA flags and an invalid set of CXX flags ( for CUDA )
#to make sure we don't use the CXX flags when linking CUDA executables
