Summary:                    CUDA_COMPUTE_BUILD_PATH unnecessarily generates very
long path when source is in binary directory
Description: 
I generate .cu files in the binary directory that I then build with
CUDA_ADD_EXECUTABLE. Unfortunately CUDA_COMPUTE_BUILD_PATH will generate a path
for intermediate files based on the relative path of that .cu file to the source
directory; this may cause very long paths in the resulting building rules.

In particular it prevents building with Ninja on Linux.

Patch to fix this problem is attached: it makes the path relative to the current
binary directory if the file is in the current binary directory.
