Summary0012099: Unable to quote cmd line args to be passed to nvcc
DescriptionI am trying to build a CUDA project with Visual Studio 2010 and CMake.

I know that this is a sensitive issue.

Basically, I get a compilation error when nvcc tries to parse a stddef.h file, and runs into the use of an undefined macro named "nullptr".

A colleague of mine had patched my VS2010/CUDA setup so that with an ordinary VS project I can properly compile CUDA source files into .obj. One of the steps involved changing the VS rules so that the command line includes the following text:

  -Xcompiler "/Dnullptr=0 /Dnullptr_t=__nullptr_t /D__nullptr=((void*)0)"

The quotation marks are essential, because otherwise the parentheses around the (void *) are parsed incorrectly. As you can see, the missing macros are defined, so that the original problem is bypassed.

However hard I tried, I could not produce the proper quotation marks to be passed as nvcc command line arguments. It came to a point that when I take the command line produced within the CMake-generated VS project (using Verbose mode), and simply add the above options, my source file get compiled. But I can't get CMake to produce the same outcome.

Example: Use the OPTIONS flag on the cuda_add_library. By default, this simply separates the -Xcompiler from the rest of the stuff, and creates an invalid command line, where "Xcompiler" becomes one of the options for Xcompiler. If I remove the "-Xcompiler" then I can't get the quotation right around the options, and then the parentheses scramle things up.

It looks as though something is wrong in the way that the OPTIONS are parsed. I can't pinpoint the issue, and I can't get around it.
Steps To ReproduceYou can use an empty .cu file.

project(Test_CMake)

find_package(CUDA)

if(NOT CUDA_FOUND)
    message(SEND_ERROR "CUDA package not found!")
endif()

cuda_add_library(Test_CMake emptyfile.cu)


Try the various options.

 I continued to check on this issue, and I think I found out why the wrong quotation marks. In file run_nvcc.cmake, line 72:

  set(CUDA_NVCC_FLAGS "@CUDA_NVCC_FLAGS@;;@CUDA_WRAP_OPTION_NVCC_FLAGS@")

Notice the quotation marks wrapping around two variables. If any of the variables contains quotes of its own, it's screwed.

Two possible ways to address this:
1) Add "ESCAPE_QUOTES" in FindCUDA.cmake, line 1031
2) Remove teh quotes from run_nvcc.cmake.

 I marked this as a duplicate of 0011726, which deals with the same quote problem. Hopefully I'll get to this soon and fix all of these.

 This should be fixed in the 2.8.7 RC. Please try it and make sure it works for you.
