Summary0016027: nvcc encloses -ccbin argument with gratuitous quotation marks during intermediate-link phase
DescriptionI'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 Reproduce1. 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
TagsNo tags attached.

 Thanks. Please try this fix:

 Brad, glancing at the patch, this will most probably work for me since I don't use MSVC, but - will it really work users who do? Are you sure you've not just narrowed the problem?

 Re 0016027:0040747: What happened between CMake 3.4 and 3.5 is there was a bug report complaining that certain source/build tree names could not be used because the generated custom commands would not quote their names correctly. To fix this the VERBATIM option was added to our add_custom_command call. When that was done the explicit quoting on the line in question here should have been removed because the VERBATIM option will take care of it. Then it turned out that the special $(VCInstallDir) syntax could not be used in combination with VERBATIM so we added a special case to not use VERBATIM if that value appears. The patch I linked in 0016027:0040745 accounts for both possibilities.

 The main reason these regressions appeared is that no one has ever set up testing infrastructure for the FindCUDA module. If anyone is interested in doing this, please come to the dev list:

 The fix in 0016027:0040745 has been queued for merge to 'release' for inclusion in CMake 3.5.1.

 Ok by me. I'm afraid I won't have time to devote to helping you with testing, though. I can promise to complain if you break something and it makes it to my distro...
