Summary:                    FindCUDA.cmake passes directory COMPILE_DEFINITIONS
to nvcc without handling generator expressions
Description: 
A colleague noticed this while using UseQt4.cmake which since 3.0 contains:
set_property(DIRECTORY APPEND PROPERTY COMPILE_DEFINITIONS
$<$<NOT:$<CONFIG:Debug>>:QT_NO_DEBUG>)

To recreate the old behaviour generator expressions could be stripped with the
new string(GENEX_STRIP) or perhaps even expanded with file(GENERATE).

Steps to Reproduce: 
cmake_minimum_required(VERSION 3.0)

set_property(DIRECTORY APPEND PROPERTY
    COMPILE_DEFINITIONS $<$<NOT:$<CONFIG:Foo>>:NOT_FOO>
)

find_package(CUDA REQUIRED)

cuda_add_library(empty empty.cu)
