The macros CUDA_COMPILE, CUDA_COMPILE_PTX, CUDA_COMPILE_FATBIN, and
CUDA_COMPILE_CUBIN were broken by commit 7ded655f (FindCUDA: Take NVCC
include directories from target properties, 2016-08-16).  This bug is
due to the fact that all of these macros call CUDA_WRAP_SRCS with a
target name that's not an actual target, causing the new generator
expressions to fail.

Fix the bug by changing these macros to pass "PHONY" to CUDA_WRAP_SRCS.
Now, when CUDA_WRAP_SRCS sees "PHONY", it falls back to the old behavior
of populating the include directories and compile definitions from
directory properties, instead of using target generator expressions.
