[CMake] No mechanism to set -Xcompiler options with Visual Studio CUDA integration?

[Hancox, James]

Hi Brad,

I picked up rc4 (since according to the release notes it has your changes merged in) and tried it out. Sadly I'm still running into problems! It looks like a semicolon is incorrectly added when -Xcompiler is appended to AdditionalOptions:

<AdditionalOptions>-lineinfo;-Xcompiler="/bigobj -Zi -Ob1"</AdditionalOptions>

This causes MSBuild to fail with the following error message:

1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\BuildCustomizations\CUDA 8.0.targets(635,9): error MSB5016: The name "-Xcompiler" contains an invalid character "-".  C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\BuildCustomizations\CUDA 8.0.targets

I tried manually replacing the semicolon with a space, and this fixes the issue for me (and -Xcompiler is passed through as expected). 

I've created a minimal test case to reproduce the error, and put it on Github at https://github.com/jameshancox/cmake_example_xcompiler , hope it helps.

Cheers,
James

It should be in a nightly binary from here:

 https://cmake.org/files/dev/?C=M;O=D

The cmake-3.9.20170621-g87dac-win64-x64.zip file should have it and can be extracted and used without installing.
