Summary:                    Building CUDA files fails when source path contains
parenthesis
Description: 
When working in a source path containing "()" I get the following error upon
building CUDA files:

15:13 sandbox$ make
[  6%] Building NVCC (Device) object
CMakeFiles/githash.dir//./githash_generated_float3.cu.o
/bin/sh: 1: Syntax error: "(" unexpected

make[2]: *** [CMakeFiles/githash.dir/./githash_generated_float3.cu.o] Error 2

make[1]: *** [CMakeFiles/githash.dir/all] Error 2
Makefile:76: recipe for target 'all' failed

The following fix provided by ngladitz in #cmake solves the issue on my machine:

diff --git a/Modules/FindCUDA.cmake b/Modules/FindCUDA.cmake
