Summary:                    nvcc encloses -ccbin argument with gratuitous
quotation marks during intermediate-link phase
Description: 
I've been using CMake on Debian Stretch with CUDA. I'm not sure what the version
was until recently, but everything worked fine for me. Then I started getting
errors such as:

"/usr/local/cuda/bin/gcc": No such file or directory
CMakeFiles/tester.dir/build.make:2335: recipe for target
'CMakeFiles/wherever/foo.o' failed

The culprit seems to be /usr/share/cmake/Modules/FindCUDA.cmake, line 1554.
Pseudo-patch:

-      list(APPEND nvcc_flags -ccbin "\"${CUDA_HOST_COMPILER}\"")
+      list(APPEND nvcc_flags -ccbin "${CUDA_HOST_COMPILER}")

that resolves the issue.

Steps to Reproduce: 
1. export CC=/link/to/your/appropriate/gcc
2. cmake a project with CMakeList.txt which finds CUDA and with
set(CUDA_SEPARABLE_COMPILATION ON)
3. Build the project

The .cu files will compile, the intermediate-link phase won't pass
